Thames Valley Police has released an E-fit of a man it would like to speak to in connection with an indecent exposure in Furzton Lake, on Thursday.
At about midday, a 32-year-old woman, was walking her dog around Furzton Lake heading towards The Bowl when she noticed a man standing near the star monument. As she approached, the man walked away from her but as he moved away he looked back to her three times.
Moments later the victim looked back and saw the man had his trousers around his knees and he was touching himself inappropriately. She shouted at him but he ignored her.
As she called the police, he left the area through the bush towards the car park off the V4.
The man is white with a chubby face, in his late twenties or early thirties, with an athletic build and around 5ft 11ins. He had blonde hair that looked unkept. He was wearing dark navy blue tracksuit bottoms which looked dirty.
The bottoms were tucked into builder type boots which were dark brown or black. The boots went to his mid calf and were laced up the front although they were not done up and looked dirty. He was wearing a white short sleeve polo shirt with coloured stripes.
Officers believe the man is local as he was seen in the area about three days before the incident although nothing happened on that occasion.
Sergeant Vanessa Wilson from Milton Keynes police station said: “I would like to hear from anyone who can help identify the man shown on this E-fit.”
Any witnesses can call police on 101.
