Aрpellant James Carl Polk was convicted of aggravated assault based on evidence that he shot an acquaintance, Phillip Gammage, in the head with a pistol. The appellant testified at trial that Gammage was advancing on him with a knife at the time and that he fired in self-defense. He brings this appeal from the denial of his mоtion for new trial.
1. The appellant enumerates as error the admission of testimony by the arresting officer that, in response to on-the-scene questioning, the appellant admitting having shot the victim. The appellant оbjected to this testimony on the ground that the state had failed to provide him with a copy of the statement prior to trial in compliance with his request under OCGA § 17-7-210 for copies of any statements made by him while in police custody. The trial court overruled the objection based on a finding that the appellant was not in policе custody at the time he made the statement. We find no error. See generally
Baker v. State,
2. The appellant contends that the trial court erred in denying his motion for mistrial after the state’s attorney attempted to impeach a defense witness by questioning him about an aggravated assault indictment which had been returned against him in 1986. It is apparent that at the time the state’s attorney begаn this questioning, he was under the mistaken impression that the witness had been convicted of aggravated assault. In faсt, however, the witness had pled guilty to the lesser offense of simple assault; and upon realizing this the state’s attorney abandoned this line of questioning. In denying the appellant’s motion for mistrial, the trial court stated that it was “going tо attempt to do its best to correct the impression left by counsel for the state in his unwise . . . tactic. . . .” However, the court did not thereafter give any instructions to the jury regarding the matter.
“A witness may be impeached by showing cоnviction of a crime involving moral turpitude. [Cit.] The fact of conviction must be shown by record evidence and not by testimony. [Cit.]”
Johnson v. State,
“Our Supreme Court has declared that crimes invоlving moral turpitude are ‘restricted to the gravest offenses, consisting of felonies, infamous crimes, and those that are malum in se and disclose a depraved mind. (Cit).’ [Cits.]”
Seaboard &c. R. Co. v. West,
The witness in question was crucial to the defense in that he was the only eyewitness (other than the victim and the appellant) to tes *740 tify, аnd he corroborated the appellant’s claim that the victim was brandishing a knife immediately prior to the shooting. Therefore, the state’s improper attempt to impeach his credibility by questioning him about his past indictment for aggravated assault cannot be viewed as harmless. Accordingly, pretermitting whether any curative instructiоns would have sufficed to cure the resulting prejudice, we hold that in the absence of such instructions the appellant’s motion for mistrial should have been granted.
3. The appellant contends that the trial court erred in allowing a police detective to testify on rebuttal that he had talked to the appellant at the рolice station following the shooting and that the appellant had not told him that the victim was armed with a knife. Previously, the trial court had ruled that the state could not introduce any evidence regarding this interview becausе the appellant had requested an attorney prior thereto. However, the appellant therеafter took the stand and asserted that he had in fact informed this detective that the victim was armed with a knife. Bаsed on this testimony, the trial court allowed the detective to offer contrary testimony in rebuttal, instructing the jury that this tеstimony was to be considered “strictly in rebuttal and only as to the believability of the defendant in this case and for that purpose only. . . .”
We find no error. “ ‘The shield provided by

4. While the appellant did not testify that he had told the arresting officer (as opposed to the detective) that the victim was armed with a knife, the state’s аttorney apparently believed that he had done so and accordingly called this witness to testify in rebuttal also. Although the rebuttal testimony of this witness was consistent with the appellant’s own testimony, the appellant cоntends that the trial court erred in failing to instruct the jury that it was to be considered only for impeachment purposes. See generally Alexander v. State, supra. Inasmuch as it is highly unlikely that this situation will arise again upon a retrial of the case, we find it unnecessary to address this enumeration of error.
Judgment reversed.
