A MAN indecently exposed himself to a woman on a disused playing field, Darwen police say.

The offender, said to be aged 45-50, was seen near to some bushes on an area known as the Moss, near Rivington.

His trousers were down and he exposed himself to a woman who was out walking her dog.

The woman told police she had earlier seen the man pass her in a black saloon car with yellow taxi plates.

The man was described as white, 5ft 9in with a 'beer belly'.

He had dark grey hair and wore a cream shirt and dark trousers.

DC Paul Ryan, of Darwen CID, said it was "a serious offence".

He said: "People sometime start off with crimes like this but then progress into offences much more serious. He must be caught."

Anybody with information should contact Darwen CID on 01254 353842 or Crime Stoppers on 0800 555 111.
