A SICK sex attacker pounced on a nine-year-old boy and indecently assaulted him as he played in a churchyard with his young brother.

The victim was attacked in grounds off Roman Road, Blackburn, between 7pm and 7.30pm last night.

Police are appealing for anyone who saw anything suspicious in the area to contact them on 51212.

Acting Detective Chief Inspector Neil Smith said: "This is a particularly nasty assault and we need to catch this man as soon as possible before he strikes again."

It is believed the attacker may be known by local people or could be a vagrant who has been sleeping rough in the area.

He is between 30 and 40 years old, 6ft 2in tall and slim, with a slight tan and dark brown hair in a crew cut. He was wearing a white T-shirt and black trousers.
