OPINION OF THE COURT
Defendant appeals, leave having been granted by a Judge of *635 this Court, from the denial of his omnibus motion to suppress his confession and physical evidence seized pursuant to a search warrant, both obtained in connection with the November 27, 1994 robbery-murder of the store clerk of a Citgo station mini-mart at Exit 23 of the North way in the Town of Lake George, Warren County.
During the initial police investigation of the Citgo homicide, the police recovered a spent bullet which laboratory analysis later determined had been fired from a .22 caliber older model gun. This information and the statement of an identified informant, Christopher Mackrodt, largely comprised the basis for the warrant. Mackrodt gave his statement with notice that any falsity would subject him to criminal sanctions under Penal Law § 210.45.
Mackrodt related that, when visiting the home of codefendant David McCulloch and in the presence of defendant and codefendant Francis Anderson, he was shown: an older-looking .22 caliber revolver, black-colored with a wooden handle; a .357 caliber revolver; and a third gun which he described in appearance but could not otherwise identify. In his subsequent visits to the McCulloch residence, defendant, McCulloch and Anderson disclosed to Mackrodt that they had stolen the three guns from Thompson’s Garage in Lake George Village, and that they were thinking of robbing the Citgo station at Exit 23 of the Northway.
Submitted with the search warrant application for the Mc-Culloch residence was documentary verification of the December 7, 1993 burglary of Thompson’s Garage, in which three guns were stolen, a Huger Blackhawk .357 caliber revolver, a Charter Arms .22 caliber revolver and a P38 Walther semiautomatic pistol. The applicant, Investigator William VanNess of the Warren County Sheriffs Department, opined that the .22 caliber revolver was the weapon used to murder the Citgo clerk. He sought authority to seize all three weapons and the proceeds of the Citgo robbery. The warrant authorized those seizures.
The search warrant was executed at McCulloch’s home on Diamond Point, Lake George, in the early evening of December 1, 1994. Sheriffs Department Investigator Robert Snyder and New York State Police Investigator Michael Huskie arrived at that site with the search party from both police agencies. They asked defendant to accompany them to the Sheriff Department’s substation for an interview. The suppression court made *636 findings that defendant willingly accompanied the officers, and was advised of his Miranda rights upon arrival at the Lake George substation.
It is uncontested that the initial questioning of defendant by Snyder and Huskie concerned his involvement in the Thompson’s Garage burglary and gun thefts and that questions on that subject were interspersed with questions on his participation in the Citgo robbery and murder. This pattern of questioning continued throughout the interrogation, until defendant gave a full written confession to complicity in the latter crimes several hours later.
It is also undisputed that defendant had been a suspect in the Thompson’s Garage crimes for some time prior to December 1994, and that in the spring of 1994 the police, notably Investigators Snyder and Huskie, had personally been advised by an attorney that he represented defendant and that defendant was not to be questioned on the Thompson’s Garage burglary and weapons theft except in his presence.
The search of the McCulloch residence eventually resulted in the discovery of the .357 caliber revolver, the P38 Walther pistol and, secreted in the attic, a blue nylon gym bag containing the .22 caliber revolver, ammunition, and United States currency in a clear plastic bag.
Following the indictment of defendant, McCulloch and Anderson for intentional and felony murder and robbery, first degree, at the Citgo station, defendant moved to suppress both the physical evidence seized under the search warrant and his confession. Among the grounds urged before County Court regarding the seizure of physical evidence was that informant Mackrodt’s arrest, on the very day of the suppression hearing, for the Thompson’s Garage crimes demonstrated the falsity of his statement and thereby invalidated the search warrant. Defendant also argued before that court that his confession should be suppressed because the officers’ interrogation violated his State constitutional right to counsel which had indelibly attached in connection with the Thompson’s Garage criminal investigation.
County Court rejected those and other grounds for suppression and denied defendant’s motion in all respects. Defendant then pleaded guilty to second degree murder. The Appellate Division affirmed (
I
Addressing, first, defendant’s argument attacking the validity of the search warrant because of the implications of Mackrodt’s subsequent arrest for the Thompson’s Garage crimes, we agree with the Appellate Division that the subsequent arrest was insufficient on this record to invalidate the warrant. Granting suppression based on the demonstrated lack of veracity of a search warrant applicant is designed to deter and penalize the knowing or reckless submission of false information by law enforcement officers, not to open the door to evidentiary impeachment of their sources.
"The requirement that a warrant not issue 'but upon probable cause, supported by Oath or affirmation,’ would be reduced to a nullity if a police officer was able to use deliberately falsified allegations to demonstrate probable cause, and, having misled the magistrate, then was able to remain confident that the ploy was worthwhile” (Franks v Delaware,438 US 154 , 168).
Thus, the United States Supreme Court expressly limited this avenue of suppression to instances of deliberate falsity or reckless disregard on the part of law enforcement affiants. "The deliberate falsity or reckless disregard whose impeachment is permitted today is only that of the affiant, not of any nongovernmental informant” (id., at 171 [emphasis supplied]).
The record of the instant suppression hearing is barren of any evidence that when Investigator VanNess applied for the search warrant he knew or recklessly disregarded evidence that Mackrodt had participated in the Thompson’s Garage burglary and weapons theft. VanNess did not swear or affirm to the truth of his informant’s statement, nor was he required to do so in order to establish probable cause
(see, People v Sulli

We reach a different conclusion with respect to the validity of defendant’s confession. The uncontested evidence at the suppression hearing was that the police initiated their interrogation of defendant with questions concerning his participation in the Thompson’s Garage burglary and weapons theft, and thereafter persisted in intermingling questions on that subject throughout the interrogation until defendant had fully incriminated himself on the Citgo murder and robbery. The officers admitted that they questioned defendant on the Thompson’s Garage matter because they believed that the Citgo murder weapon was one of the guns stolen during the garage burglary. Thus, for the police, the two crimes were concededly related; proof of defendant’s participation in the burglary and gun larceny at the garage would be probative of his involvement in the crimes committed at the Citgo station.
Our case law involving police interrogation of a suspect on the subject of one crime after the right to counsel had indelibly attached by the actual appearance of an attorney representing that suspect in another crime falls into two relevant categories.
*
The first of these is where the two criminal matters are so closely related transactionally, or in space or time, that questioning on the unrepresented matter would all but inevitably elicit incriminating responses regarding the matter in which there had been an entry of counsel. In such cases, interrogation on the unrepresented crime is prohibited even in the absence of direct questioning regarding the crime on which
*639
counsel had appeared. Thus, in
People v Townes
(
"Here, the subject of the interrogation and the subject of the criminal charges are so inextricably interwoven in terms of both their temporal proximity and factual interrelationship as to render unavoidable the conclusion that any interrogation concerning the arrest would almost inevitably involve some potentially incriminating discussion of the facts of the crime itself. To separate the arrest from the crime itself and more importantly, to ask the defendant to make that distinction is to seek to draw far too fine a line” (41 NY2d, at 104 , supra).
Similarly, in
People v Vella
(
The instant case does not fall into the foregoing category, where the represented and unrepresented crimes are so thoroughly interrelated that questioning on one will almost necessarily elicit incriminating responses on the other. Discrete *640 questioning of defendant concerning the Citgo crimes, by a police officer mindful and respectful of the indelible attachment of defendant’s right to counsel regarding the Thompson’s Garage matter, would not have created any serious risk of incriminating responses as to the latter crimes. Thus, the police officers would not have been wholly barred from questioning defendant on the Citgo crimes merely because he was already represented by counsel on the Thompson’s Garage investigation.
More to the point here, however, is a second line of precedent involving interrogations concerning crimes less intimately connected, but where the police were aware that the defendant was actually represented by an attorney in one of the matters. Concededly in those cases, the interrogation actually entailed an infringement of the suspect’s State constitutional right to counsel by impermissible questioning on the represented crime.
Thus, in
People v Ermo
(
Applying the foregoing precedents to the instant case, we note that the Appellate Division utilized the wrong legal standard in basing its decision on the conclusion that the questions regarding the Thompson’s Garage crimes "were not
the
crucial element in securing defendant’s confession” (citing
People v
*641
Ermo, supra
[emphasis supplied]). Thus, that Court would limit suppression in intermingled interrogations to cases where concededly improper questioning on one crime, in violation of a defendant’s State constitutional right to counsel, was the single critical causal element in obtaining the confession to the unrepresented crime. This approach misses the emphasis we have placed on the factor that the "impermissible questioning * * * was not discrete or fairly separable”
(People v Ermo, supra,
The Appellate Division’s analysis also fails to take into account the element we identified as "critical” in
Ermo,
that the police
purposely
"exploited concededly impermissible questioning” in order to obtain a confession in the unrepresented matter
(see, People v Ermo, supra,
at 865). In
People v Ruff
(
In most cases the impetus for a suspect to confess will arise out of a complex and often not completely known set of factors. Moreover, just as in this case, a suppression court often will not have the benefit of a full transcript of the interrogation from which to make a comprehensive assessment of the role played by impermissible questioning in securing a suspect’s confession. Thus, the Appellate Division’s standard for suppression, that the impermissible questioning must demonstrably have been the crucial element in the confession on the unrepresented matter, would provide little disincentive for the police to engage in wrongful practices which violate a suspect’s State constitutional right to counsel.
In our view, the undisputed facts and the unassailable inferences therefrom
(see, People v Ferro,
Additionally, the concessions by the officers in their testimony at the suppression hearing demonstrate as a matter of law that the questioning on the Thompson’s Garage matter was purposely exploitive
(id.; see also, People v West,
Under the foregoing undisputed facts and necessary inferences, the People had a heavy burden to demonstrate that defendant’s confession to the Citgo robbery and murder was uninfluenced by the taint of the violation of defendant’s State constitutional right to counsel
(compare, Brown v Illinois,
Accordingly, the order of the Appellate Division should be reversed, defendant’s motion to suppress statements granted, and the matter remitted to County Court for further proceedings in accordance with this opinion.
Chief Judge Kaye and Judges Titone, Bellacosa, Smith, Ciparick and Wesley concur.
Order reversed, etc.
Notes
A third category, not pertinent here, prohibits the questioning of a defendant on any matters, whether related or unrelated, when defendant is in custody on the charge upon which the right to counsel has indelibly attached (see,
People v Burdo,
