The NYPD is investigating a threatening note sent to a Brooklyn mosque that was signed "Muslim Slayer."
Imam Ibrahim Yavas of the American Turkish Eyup Sultan Cultural Center told police he got the letter on 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.
