A subway rider who apparently tried to make the train a better place was attacked in Brooklyn last month, according to police.

The NYPD says that shortly after midnight on June 6th a group of four males was on a southbound G train "where they were cursing and acting disorderly." A 45-year-old man "asked them to refrain from cursing. A dispute ensued and the suspects began to punch the victim about the head as he exited the train at the Smith and 9th Street station."

The victim suffered bumps and bruises to his head.

The suspects fled, but the police released surveillance images of them. Anyone with information in regards to this incident is asked to call the NYPD's Crime Stoppers Hotline at 800-577-TIPS.
