Police have released this e-fit of a man suspected of indecently exposing himself to a dog-walker in Puddletown Forest.

The incident happened at around 10.15 am on Saturday, March 17, in the wooded area outside Dorchester.

The victim - a woman aged in her fifties - was walking her dog in the forest, but had lost her bearings and flagged down a passing cyclist to ask for direction.

As the cyclist gave her directions, he indecently exposed himself.

The victim turned away from the flasher and began to take out her phone, at which the man remounted his bicycle and rode off at speed.

The woman was not physically hurt.

The offender is described as a white man in his forties, with dark but greying hair. He was of average build and was wearing glasses with a silver frame, black Lycra cycling trousers with a yellow strip, a dark long-sleeved zip-up top, dark shoes and dark gloves, along with a black cycling helmet.

He was riding a purple-framed mountain bike.

Police Constable James Curtis of Dorchester Police said: "This incident has understandable left the victim shaken, and I am now in a position to issue an e-fit of the suspect.

"I would ask that anyone who may recognise the man from the image to please contact Dorset Police or call Crimestoppers anonymously.

"Officers have stepped up patrols in the area over the last few weeks and anyone with concerns can contact the neighbourhood policing team."
