Defendants filed a joint brief in this appeal. 1 Defendant Shane argues six assignments of error, two of which are also properly raised by defendant Williams. We are persuaded, after a careful review of the applicable law and the circumstances of this case, that both defendants are entitled to a new trial upon the charges of sexual crimes. We shall address defendants’ mutual assignments of error first.
I.
Defendants contend that the trial court erred in permitting the State to cross-examine Shane about a prostitute’s performance of fellatio upon him, seven months prior to the occurrence of the charged events at the Tahiti Health Club, while he was employed as a police officer in Fayetteville. It is well established that a criminal defendant may be cross-examined about prior acts of misconduct, even if he was not convicted therefor, for the purpose of impeachment, provided the questions are asked in good faith.
State v. Lynch,
From the outset of his inquiry into this subject, the prosecutor focused upon the circumstances surrounding the termination of Shane’s previous employment with the Fayetteville Police Department:
Q. You resigned from the intelligence unit because of sexual improprieties, didn’t you?
WITNESS: I resigned from the intelligence police department because a prostitute downtown made allegations against me; and for the betterment of the department and myself, I resigned.
Mr. RAND: In resigning, you told Mr. Bill Johnson, did you not, about this incident?
MR. RAND: You told Mr. Johnson, did you not, about this matter; that you just weren’t thinking; that all you were doing was getting a shot of cock, didn’t you?
WITNESS: I did not sir.
Mr. RAND: You did not tell him that?
A. I did not, sir.
Q. Mr. Johnson is the head of the intelligence unit, isn’t he?
A. Yes, sir, Mr. Bill Johnson.
*650 Q. You talked to Mr. Johnson about this alleged incident with the prostitute, didn’t you?
WITNESS: Yes, sir, I did.
Mr. RAND: It involved oral sex, didn’t it?
WITNESS: It was an allegation that was made —
Mr. RAND: It involved oral sex, didn’t it?
WITNESS: I don’t know sir. I know it involved some allegation.
MR. RAND: You were certainly informed of the allegations by your superiors, weren’t you?
WITNESS: I was informed of — yes, sir, I was.
Mr. RAND: And you know it involved oral sex, didn’t you, by you when you picked up a girl and asked her what she would do to keep from getting busted?
Mr. RAND: Didn’t you?
WITNESS: No, I did not.
[Defendants’ duly entered, but overruled, objections, motions to strike and exceptions to this questioning are omitted.] Defendants attack the method of the foregoing inquisition about Shane’s past bad acts upon two bases: (1) its impermissible inclusion of references to mere allegations of misconduct and (2) its failure to identify directly a specific instance of reprehensible behavior.
*651
Though a defendant’s former evil exploits or iniquities are “fair game” during cross-examination, as a means of challenging his veracity, the mode of the inquiry is not without limitation. First, the prosecutor may not attempt to impeach a defendant’s character by asking about, or referring to, prior arrests, indictments, or any other accusations of misconduct.
State v. Williams,
A legitimate inference of foul play does not invariably arise from the mere act of resigning from employment. Moreover, the term “improprieties” is overly broad because an improper act
*652
does not necessarily connote a breach of moral or legal mores, and the plural form of the word suggests the commission of several acts without particularizing a single, specific event for the jury to consider in evaluating credibility.
See State v. Purcell, supra; State v. Mason, supra.
Defendant Shane was never asked outright whether he had engaged in an earlier sexual misdeed with a prostitute. Instead, Shane was interrogated about his prior
conversations
with another police officer about the incident and his
knowledge
of the content of the prostitute’s allegations. Thus, we conclude that the prosecutor’s cross-examination of Shane was not competently tailored to elicit his affirmance or denial of “some identifiable specific act” by means of a
detailed
reference to “the time or the place or the victim or any of the circumstances of defendant’s alleged prior misconduct.”
State v. Purcell, supra,
II.
Defendants additionally argue that the trial court erroneously denied their motion to suppress the rebuttal testimony of Officer William C. Johnson, Shane’s former supervisor in the intelligence division of the Fayetteville Police Department. Specifically, Officer Johnson testified that he had two conversations with Shane on 10 and 11 July 1979 about allegations by “another individual” involving oral sex. Officer Johnson said Shane told him the following things in the course of their conversations: (1) that the incident had occurred; (2) that no force had been used during the event; and (3) that “he just was not thinking; that he only got a shot of cock.” Simply put, the issue is whether this rebuttal evidence was competent under any theory of admissibility. We hold that it was not.
First, Officer Johnson’s testimony was certainly not admissible, as the State argues, to impeach defendant Shane’s trial testimony about the alleged sexual impropriety of July 1979 with his own prior inconsistent statements. For, the rule is well settled in this jurisdiction that, though a witness’s character or propensi
*653
ty for telling the truth is subject to impeachment through cross-examination about specific instances of misconduct or prior inconsistent statements, the witness’s answers to such questions are conclusive, and he may not be further impeached or contradicted through the introduction of
any kind
of extrinsic evidence.
State v. Dawson,
Second, Officer Johnson’s testimony was also not admissible for any other competent purpose in this case. Receipt of extrinsic evidence disputing defendant Shane’s testimony would have been permissible
only if
the evidence about his prior misconduct exhibited a distinct materiality or relevancy, beyond its mere capacity for impeachment, and thus could have been properly proven as part of the State’s case in chief.
See State v. Taylor,
By virtue of a sound legal axiom, substantive evidence of a defendant’s past, and distinctly separate, criminal activities or
*654
misconduct is generally excluded when its only logical relevancy is to suggest defendant’s propensity or predisposition to commit the type of offense with which he is presently charged.
State v. McQueen,
At the outset, we acknowledge that our courts, as well as those of other jurisdictions, have been “very liberal” in admitting evidence of similar sexual offenses under one or more of the exceptions listed above.
State v. Greene,
In the case at bar, there is indeed a striking similarity between the alleged factual occurrences at the Tahiti Health Club on 10 February 1980 and defendant Shane’s alleged encounter with a prostitute in July 1979. Among other things, the State’s evidence tended to show that on both occasions, Shane, flaunting his authority as a police officer, requested illicit sexual favors in return for his agreement to drop criminal charges of prostitution against the women and that the women subsequently performed fellatio upon him, either by consent or force. However, these events occurred at different places, involved different women, were separated by a period of
seven months,
and, in the latter occurrence, included the participation of another partner in the crime. In an analogous case,
State v. Gammons,
the defendant, a preacher, was accused of assault with intent to commit rape upon a female member of his church after he had lured her into a basement bedroom in his house on a religious pretext (to pray).
Thus, we hold that the rebuttal testimony of Officer Johnson constituted improper impeachment of defendant Shane’s testimony upon a collateral matter and was not admissible as substantive evidence of a similar offense. The prejudicial and inflammatory impact of the incompetent evidence is obvious under the circumstances of this case, and its erroneous admission requires a new trial of both defendants.
III.
At this juncture, the State argues that defendant Williams is not equally entitled to a new trial for the foregoing error because the trial court specifically instructed the jury not to consider the challenged rebuttal evidence in determining his guilt or innocence. However, the record plainly refutes the State’s contention. We quote the portion of the judge’s charge relied upon by the State:
During cross examination of codefendant Stanford Anthony Shane, he was questioned regarding circumstances surrounding his termination as an employee of the . . . Fay-etteville Police Department. This testimony was admitted for the sole purpose of impeaching the credibility of said code-fendant if, in fact, you find that it does impeach his testimony. Therefore, you are instructed that the questions and answers concerning employment of the codefendant Stanford Anthony Shane are not to be considered as evidence of *657 guilt of the defendant Dean L. Williams. Therefore, I instruct you that the questions and answers concerning the employment of the defendant Shane with the Fayetteville Police Department are to be considered for no purpose whatsoever in determining the guilt or innocence of Dean L. Williams.
(Record, p. 106 (emphasis added).)
We find that these instructions adequately and correctly informed the jury to disregard the evidence of Shane’s prior misconduct elicited during his
cross-examination
in reaching a verdict upon the charges against defendant Williams. The instructions did not, however, expressly mention Officer Johnson’s similar testimony and did not, therefore, clearly admonish the jury to ignore this incompetent evidence in its deliberations against Williams. This being so, and it duly appearing that defendants’ defenses were so inextricably interwoven that the jury could only rationally find both of them equally guilty, or not guilty, of committing the sexual offenses at the Tahiti Health Club, we hold that defendant Williams must also receive a new trial in the interests of the fair administration of justice and the policy favoring consistency of verdicts in the same cause.
See May v. Grove,
IV.
In sum, we hold the following: (1) defendant Shane’s prior misconduct with a prostitute was a proper subject of cross-examination to impeach his character and credibility; (2) the prosecutor’s questions in that regard were not, however, propounded in a precise and permissible fashion; (3) extrinsic evidence, in the form of Officer Johnson’s rebuttal testimony, was not admissible to contradict defendant Shane’s denials regarding prior misconduct; (4) Officer Johnson’s testimony was also not admissible as substantive evidence of a similar offense; and (5) the erroneous admission of such extrinsic evidence requires a new trial of both defendants.
Our disposition of the case renders consideration of defendant Shane’s additional, separate assignments of error unnecessary, as such errors are not likely to recur at the next trial.
In conclusion, we note that the State’s evidence, if believed, showed that these defendants travelled the sordid road of Sodom and Gomorrah yet, by the judgments imposed upon them, would have been subjected to a fate far less severe than that which *658 befell those two cities. Even so, we must reluctantly disturb the jury verdicts, due to the commission of a serious and harmful error at trial, to enforce defendants’ fundamental right to an impartial adjudication of their guilt. However, we find that the eviden-tiary error only presented a reasonable probability of improperly influencing the trial outcome regarding the sexual offenses and thus uphold the verdicts rendered against both defendants on the common law robbery counts. As the trial court consolidated the judgments against defendant Shane for the robbery and an attempted sexual offense, we must remand for separate re-sentencing upon his robbery conviction alone.
New trial, of both defendants, upon the charged sexual offenses.
No error in defendants’ convictions for common law robbery.
Remanded for re-sentencing of defendant Shane upon his robbery conviction.
Notes
. In their brief, defendants only listed the pertinent exceptions in the record under each question presented for review. Rule 28(b)(3) of the North Carolina Rules of Appellate Procedure states that the specific assignments of error, being relied upon in support of the corresponding argument, should also be set out under each question.
. William C. Johnson, Commander of the Intelligence Division of the Fayette-ville Police Department, testified on voir dire examination that he had *649 turned over the results of an internal investigation of the matter to the district attorney’s office for its determination of whether the circumstances warranted a criminal prosecution against Shane. In fact, the State unsuccessfully tried to introduce a copy of that very report at trial.
. If the rule were otherwise, a witness could be placed in the untenable position of having to defend himself against unproved insinuations or rumors of past behavior in order to maintain his testimonial credibility at an unrelated trial.
. The general prohibition against double impeachment of a witness upon a matter not directly in issue makes good common-sense. For, the development of a “mini-trial” upon a defendant’s guilt of some collateral misconduct or the presentation of “an interminable series of contradictions of a witness’s testimony about a point of minor relevancy would confuse the jury and unnecessarily distract its attention from the true issues presently being tried.
See State v. Royal,
. It should be noted that, in this case, there was never any issue about the identity of the alleged sexual assailants. Throughout the criminal investigation, the employees of the Tahiti Health Club positively and consistently identified Shane and Williams as the perpetrators of the charged offenses. In addition, Shane and Williams did not tender an alibi defense —they plainly admitted that they were at the club at the times in question. The sum and substance of the case was simply determining who was telling the truth about whether Shane and Williams had actually committed any sexual crimes while they were at the club.
. The facts are more fully explicated in a subsequent opinion rendered in the case reported at
