MEMORANDUM.
The order of the Appellate Division should be reversed.
On the return of a writ of habeas corpus, the scope of *761 inquiry is "only as to the legality of the denial of bail, as to whether or not the denying Court has abused its discretion by denying bail without reasons or for reasons insufficient in law" (People ex rel. Shapiro v Keeper of City Prison, 290 N.Y. 393, 399, emphasis in original; see, also, People ex rel. Klein v Krueger, 25 N.Y.2d 497, 500-501). Relevant factors in granting or denying bail are "[t]he nature of the offense, probability of conviction, and severity of the sentence which may be imposed, all increasing the risk of flight or unavailability for trial" (People ex rel. Parone v Phimister, 29 N.Y.2d 580, 581, and cases cited therein; CPL 510.30).
Bail was denied on the grounds that (1) there was a "substantial likelihood that relator would flee" or (2) that he would "interfere with the judicial process". The first ground alone, likelihood of flight, is sufficient. In addition to the fact that relator was charged with a class A-1 felony for which the severest possible sentence may be imposed (save murder in the first degree [Penal Law, § 125.27]), the nature of the offense is heinous (see People v Broadie, 37 N.Y.2d 100) and the possibility of conviction is very high in that the arrest arose out of a transaction involving the sale of three and one half kilograms of cocaine (worth approximately $127,000) to an undercover police officer, a court authorized wiretap was made which allegedly incriminates relator and, furthermore, it is alleged that informants have linked relator to other drug sales and to organized crime. Moreover, a criminal confederate of relator revealed that he and others were prepared to post bail in order that relator might "take off". In these circumstances, we cannot conclude that it was constitutionally unwarranted to deny bail (People ex rel. Parone v Phimister, 29 N.Y.2d 580, supra; People ex rel. Shapiro v Keeper of City Prison, 290 N.Y. 393, supra).
People ex rel. Klein v Krueger (25 N.Y.2d 497, 501, supra) relied upon by relator and the Appellate Division, is not to the contrary. There we said, "In this case the only critical support actually offered for the denial of bail is not danger of flight * * * but rather the danger to potential witnesses" (p 502, emphasis added). While Klein resembles this case in that evidence of danger to potential witnesses was adduced, it stands in stark contrast insofar as evidence of flight is concerned and, thus, is inapposite.
Since fixing of bail is subject to very limited review, the responsibility of the bail fixing court is correspondingly great.
*762Although the District Attorney states that he was ready to try relator, if relator is not tried within a reasonable time, having due regard to the party causing the pretrial delay, review de novo of this bail application should not be precluded.
Order reversed, without costs, and the judgment of Supreme Court, New York County, reinstated in a memorandum.
