Police are hunting a driver who laughed as he exposed himself to a woman in Isleworth.

The man was driving slowly along Snowy Fielder Waye, around the back of West Middlesex Hospital, when he pulled up to the kerb and exposed himself at the steering wheel as a 37-year-old woman walked past.

The man was driving a maroon car, possibly a Renault Clio, which had a child seat in the back and a black and yellow children's sun driver on one window.

He is described as white, aged in his late 20s to early 30s and about 5ft10. He is skinny with thin lips and a thin nose, and had mousy hair, a beard and moustache.

His victim believes he was wearing a uniform of some sort, with cargo-style trousers and a royal blue polo top with red trim and a red logo on the chest.

The incident happened on Saturday, August 30, at about 10am but police have so far been unable to trace the culprit.

Anyone with information is asked to call DC John Cahill, of Hounslow Police, on 020 8247 6135.
