NEWARK, N.J. — The report was stamped top secret.
Inside was a confidential dossier compiled by the New York Police Department documenting "locations of concern" in Newark -- the city's 44 mosques, Muslim-owned restaurants and businesses and Islamic schools.
In 2007, the NYPD began an undercover spy operation within New Jersey's largest city to find and document where Muslims lived, worked and prayed.
Now, city officials and many of those targeted are voicing anger at the disclosures, which came in the wake of an Associated Press report showing that a secret NYPD surveillance program aimed at Muslims had extended well beyond New York City.
"I have deep concerns and I am very disturbed that this might have been surveillance that was based on no more than religious affiliation," Newark Mayor Cory Booker said.
