Police are appealing for witnesses after a number of parked cars were damaged along Latimer Road in Eastbourne.
Officers received a call from a resident at around 6.40pm on Sunday, November 24 after she heard a loud noise and then found a wing mirror on her car had been damaged.
A group of between six and eight teenagers were seen running away into Channel View Road and then into Princes Park but they had left the area before police arrived.
It was later discovered that a number of other cars on Latimer Road had also been damaged.
One of the gang was a boy of large build aged 16 to 18. He was wearing a blue hooded top and grey tracksuit bottoms with writing on them. Another boy in the group was riding a bicycle.
