A group of "freerunning" youngsters have damaged a roof and a car.
Police have issued a photo of one of them who is believed to have been involved in damaging the roof of St Leonard's Church Hall, Seaford, and a nearby car.
PCSO Daniel Turk said: "We have had several compliants about youngsters climbing onto buildings in and around Broad Street and it has been suggested that they are taking part in freerunning, which can include jumping from one building to another.
"Not only is this dangerous, but it can cause damage to the buildings. We are concerned that somebody might fall and seriously hurt themselves or dislodge more tiles and masonry and injure somebody on the ground.
"We are keen to hear from anybody who knows the identity of those responsible so we can put a stop to it before somebody does get hurt or more damage is caused."
The three youths caught on CCTV on the evening of Thursday July 3 are all described as white, skinny and aged around 14-16. T
he first, in the photo, was wearing a distinctive white T-shirt with black sleeves and a logo on the front and blue jeans. A second was in a black T-shirt and shorts, wearing a white cap and carrying a black bag with a black-and-white Bench logo. The third was wearing red shorts and carrying a purple bag.
Anybody with any information is asked to contact police on 101 or email email@example.com quoting serial 1172 of 04/07.
