A 17-year-old boy was hit in the face with a bat after he was grabbed during an attack by two men.
Police are seeking witnesses to the assault in York Road, Hartlepool, as they piece together what happened and try to trace the pair.
The incident happened close to the junction with Park Road as the boy rode his bike along the street.
A man approached him and asked questions relating to his bike before grabbing the victim's clothing towards the neck area.

The victim was then struck to the fact, leaving him with a broken jaw.
Both men ran off towards Dalton Street.

He was around 6ft tall, of medium build with a clear complexion and slight stubble.
The second suspect is described as a white male, aged in his late twenties, around 5ft 10in tall, of medium build and wearing dark clothing.
