A gang of youths armed with slingshots assaulted a teenage boy in a Daventry park.
At about 2.30pm on Friday May 16, the teenager was in the Fishponds park on the Southbrook estate in Daventry.
He saw four older boys enter the park, so moved to a different area. The older boys were carrying slingshots and one of them fired a stone at the teenager, hitting him in the leg.
The youths were all about 18 and about 5ft 10in. They were all wearing white t-shirts and black trousers.
The one who shot at the boy had short dark hair and may have been wearing a black baseball cap.
Witnesses or anyone with any information about this incident can call the police on 101 or Crimestoppers anonymously on 0800 555 111.
