Police said both were intoxicated during the argument.
A drunken 42-year-old man is accused of chomping down on a teen's fingers during an argument at a Hackettstown home, police said.
Officers at 3:05 p.m. Friday were dispatched to the home in the 100 block of Main Street. Police found the 18-year-old male, who was not identified, with cuts to his fingers.
Police said the teen was in the bathroom when the man, who also wasn't identified, walked in and bit his fingers. The teen then followed the man into the living room and punched him in the face, according to police.
Officers determined both the man and teen were intoxicated, police said.
Both were charged with simple assault. They were sent to Warren County jail in lieu of $2,500 bail each.
Assisting at the scene was the Hackettstown Rescue Squad.
