On October 4, 1964, a murder by stabbing took place in an elevator of an apartment building where petitioner Morales’ mother lived and where Morales frequently visited. On October 13, his mother informed Morales by telephone that the police wished to talk with him; petitioner said that he would come that evening to his mother’s place of business. This he did. He was apprehended by police officers and taken to the police station, arriving at 8:30 p. m. Within 15 minutes he had confessed to the crime and by 9:05 p. m. he had written and signed a statement. In response to subsequent questioning by police officers, Morales later repeated the substance of this confession. At the trial, the court held a separate hearing on the voluntariness of the confessions, found them voluntary, and admitted them over Morales’ objection. Morales was convicted, the jury apparently rejecting his alibi defense that he was with his mother at the time of the murder. The Appellate Division of the New York Supreme Court affirmed without opinion. People v. Morales, 27 App. Div. 2d 904, 280 N. Y. S. 2d 520 (1967). In the New York Court of Appeals, Morales for the first time raised a Fourth Amendment issue, claiming that there was no probable cause for his detention at the time of his confessions and that the confessions, even if voluntary, were inadmissible fruits of the illegal detention. The State asserted that the issue had not been decided below and that there had hence been no opportunity to make a record of the relevant facts; moreover, the State claimed that Morales had voluntarily surrendered himself for questioning and that in any event the voluntary confessions were the result of an independent choice by Morales such that the legality of the detention was irrelevant to the admissibility of the confessions.

The Court of Appeals affirmed, accepting without discussion the trial court’s finding as to the voluntariness of Morales’ confessions.

v.
Morales,
22 N. Y. 2d 55,
After considering the full record, we do not disturb the determination of the trial court, affirmed by the New York appellate courts, that Morales’ confessions were voluntarily given. The trial occurred prior to
Miranda
v.
Arizona,
We should not, however, decide on the record before us whether Morales’ conviction should otherwise be affirmed. The ruling below, that the State may detain for custodial questioning on less than probable cause for a traditional arrest, is manifestly important, goes beyond
*105
our subsequent decisions in
Terry
v.
Ohio,
Given an opportunity to develop in an evidentiary hearing the circumstances leading to the detention of Morales and his confessions, the State may be able to show that there was probable cause for an arrest or that Morales’ confrontation with the police was voluntarily undertaken by him or that the confessions were not the product of illegal detention. In any event, in the absence of a record that squarely and necessarily presents the issue and fully illuminates the factual context in which the question arises, we choose not to grapple *106 with the question of the legality of custodial questioning on less than probable cause for a full-fledged arrest.
We accordingly vacate the judgment below and remand the case for further proceedings not inconsistent with this opinion.
It is so ordered.
