An unknown suspect attacked 79-year-old man on a city subway last week and struck him in the head with a high heel, police said on Thursday, Oct. 31.

It occurred at around 10:15 a.m. on Oct. 24 in Midtown Manhattan on the No. 2 train headed southbound.

The suspect started arguing with the old man while on the train, police said. He then took off a high-heeled shoe to hit the old man in the head.

Video posted on Instagram shows blood dripping from the man’s head. The woman posting the video online said the man was singing gospel songs on the train. 

Police said the suspect fled the scene.

EMS responded and the man exited the train at 42nd Street and Seventh Avenue. He was taken to NYU Hospital for a treatment.
