Police are looking for the person behind a violent incident that’s being investigated as an assault, sexual assault and hate crime in Bushwick.

It happened at the Myrtle Avenue/Broadway subway station J train platform on Thursday just after 1 p.m.

Police say a man allegedly grabbed the backside of a 22-year-old woman on the train platform, leading to an argument between the two as they got on the train.

During the dispute, police say the man uttered “anti-LGBT” language toward her.

The man then punched the woman in the face and body multiple times, fracturing her nose. The suspect fled off the train at the Delancey Street/Essex Street stop.

Police are asking anyone who may recognize the man to contact police at 1-800-577-TIPS.
