Police use Taser on naked man with knife in East Harlem playground

EAST HARLEM, NEW YORK CITY -- Police were forced to use a Taser on a naked knife-wielding man in East Harlem Thursday, and the incident was caught on camera.

Authorities received reports of an emotionally-disturbed man with a knife and no clothes inside the Martin Luther King, Jr., playground on 111th Street and Lenox Avenue around 3 p.m.

After he was ordered to drop the knife, police say the suspect exited park and crossed the street.

Officers moved in to subdue him, and onlookers gasped as one cop employed her Taser.

Other officers quickly rushed to take the man into custody.

He was transported to St. Luke's Hospital in stable condition. No serious injuries were reported.
