An audiotape has been released of the 911 emergency call that uncovered the New York City Police Department’s secret spying on Muslim neighborhoods inside New Jersey. The Associated Press revealed last year NYPD agents photographed every mosque in Newark and eavesdropped inside Muslim businesses as part of a wider anti-Muslim spying program across the Northeast. On the tape from June 2009, a building superintendent told a 911 dispatcher he had discovered a suspicious apartment as part of a routine check.

Caller: “Came across an apartment where there’s some suspicious activity.”

Dispatcher: “What’s suspicious?”

Caller: “Suspicious in the sense that the apartment has about — has no furniture except two beds, has no clothing, has New York City Police Department radios.”

Dispatcher: “Really?”

Caller: “There’s computers in there.”

Dispatcher: “There’s what?”

Caller: “There’s computer hardware, software, you know, just laying around. There’s pictures of terrorists. There’s pictures of our neighboring buildings that they have.”

Dispatcher: “In New Brunswick?”

Caller: “Yes.”

The phone call led the NYPD to admit to the FBI and New Jersey police that the spying operation was taking place. The tape was finally released after the NYPD fought to block its disclosure.
