An eight-year-old boy has been assaulted at a park in Swanwick.
The boy was with his older brother on the park off Windsor Close when they were approached by a group of 15-year-olds.
One of the them kicked the boy off a swing then kicked and punched him while he was on the floor.
The boy and his brother ran home.
When the children's father attended the park the group ran off.
Witnesses or anyone with information about the crime - which happened last Wednesday - should call police on 101 or Crimestoppers on 0800 555 111.
