A police helicopter was called out to hunt a sex pest spotted “touching himself” outside a flat in High Wycombe in the early hours of this morning.

NPAS Benson helicopter crews were used to help town centre officers search for the man at 2.10am after he was seen outside a property in Freer Crescent, off Gomm Road.

Earlier today the team tweeted about their early morning search, saying there was “no trace” of the suspect.

Thames Valley Police are now appealing for witnesses or anyone with information to call officers on 101.

The man is described as black, in his twenties or thirties, about 5ft 7-9ins, stocky and short or shaved hair.

He was wearing a T-Shirt with a semi circle logo on it and grey tracksuit bottoms.
