Two people, including a 13-year-old, were hurt after being attacked with a car club at a motel in Red Hook.
Investigators have released a surveillance photo of the man who they say clubbed the victims inside the Brooklyn Motor Inn at around midnight on May 10.
According to police, the teenager suffered a broken arm and laceration to his head. The other victim, a 29-year-old man, also had a laceration to the head. Both were treated at the hospital and later released.
The suspect is believed to be in his late 40s or early 50s, and has an either bald or shaven head.
