POLICE are warning women and children not to walk alone in isolated areas after a teenager on a bike indecently exposed himself to a woman.

The victim was walking along a canal towpath in Clayton-le-Moors when a youth, aged 14 to 17, exposed himself.

He is white, with a very pale complexion, wearing a green baseball cap, green t-shirt and beige tracksuit bottoms.

The incident follows two similar offences in woodland, near Wilson playing fields last month.
