A group of teenagers vandalised a car parked in a Corby street before fleeing.
The three youths were seen hanging around Boston Close just after 9.15pm on Wednesday, September 10.
One of the gang punched the wing mirror of a red Honda Civic, breaking it, before they ran away.
All three were white, aged 15 to 17 and wearing dark tracksuit bottoms and hooded tops.
Witnesses, or anyone with information, should call the police on 101 or Crimestoppers anonymously on 0800 555111.
