Threatening note signed 'Muslim Slayer' sent to NYC mosque

New York City police are investigating a threatening note signed "Muslim Slayer" that was sent to a mosque.

Imam Ibrahim Yavas of the American Turkish Eyup (EYE'-oop) Sultan Cultural Center in Brooklyn told police he got the letter Tuesday, mailed to his residence at the center.

The letter said the writer had a "dirty little secret" and fantasized about "killing nonwhites," including the recipient.

The hate crimes task force is assigned to the case. No arrests have been made.
