An off-duty New York City police officer is hospitalized in a medically induced coma after he was punched in the face and struck his head on a Manhattan subway platform.

Police say the 29-year-old officer was attacked around 6:30 p.m. Saturday. It happened on the southbound 6 platform at 23rd Street and Park Avenue.

Police say he was taken to Bellevue Hospital where doctors found bleeding on the brain.

Police would not identify the officer but say he’s been with the department for six years.

They say they have no motive for the attack.

They say the suspect fled with two women after the assault. They described him as between 5-foot-10 and 6-foot, about 200 pounds and wearing a white T-shirt.

Police are asking anyone with information to call 1-800-577-TIPS.
