Watchdog group sues NYPD, feds for records on cop’s murder

A watchdog group is suing the NYPD and the feds for decades-old records in the ambush and killing of a police officer at a Harlem mosque — including audio of a phony 911 call they hope may finally lead to an arrest.

Hearing the April 1972 recording — in which someone claiming to be a cop reported an “officer in distress” at the former Nation of Islam Mosque No. 7 on West 116th Street, may jog someone’s memory — Judicial Watch contends.

“Maybe even after all these years, somebody might recognize the voice,” said Micah Morrison, who works for group.

The group’s Manhattan Supreme Court suit seeks the audio recording’s release. A transcript, in which a man referencing the police code for an officer in trouble tells the dispatcher, “I have a 10-13 West 116th Street,” has long been public.
