FLATBUSH - A Fort Greene family is asking for the community's help finding the suspect who attacked their autistic son on a subway last week.

The victim, who didn't want to give his full name, says he was riding the Coney Island-bound 'B' train when a man he didn't know came up to him, punched him in the face and broke his nose.

Police say the victim was sitting in the middle of the train when a man wearing a tan hooded jacket and green jeans punched him four or five times in the face.

The victim's family says he was spending a day off from work shopping when the attack happened.

Police ask anyone with information to come forward.
