Cops are looking for an ex-con who yesterday claimed to be holding hostages in Brooklyn.

Naquone Taylor, 29, allegedly contacted detectives at the 83rd Precinct in Bushwick on his cellphone at 11 a.m., and told them he was holding hostages at an undisclosed location.

Cops went to his house on Howard and Jefferson avenues, but were not able to find Taylor.

Investigators are hoping the public can help cops nab the suspect, who served time for robbery and criminal mischief, according to state records.
