A wrench-wielding gang of teenage boys is being sought by police following an attack in Avenham Park.

The 15-year-old victim was walking in the park close to the Ribblesdale Place entrance when he was approached by a group of 10 teenage boys.

The group demanded the boy’s watch during the incident at around 8m on Thursday (18 May).

When the victim refused he was attacked with a wrench.

He suffered facial injuries including a split lip and damage to his teeth.

The boy fell to the floor and handed a watch, a Rolex Yacht Master in blue and gold, to the attackers.

Seven of the teenagers made off from the scene with three boys staying to help the victim.
