A SEX attacker is still loose in a North-East town a month after he subjected a woman to an horrific assault.

Detectives in Darlington continue to investigate the assault, which took place in the town's Green Lane on May 7.

They say there has been an excellent response to an appeal to catch a youth who attacked the woman while she was out with her two children, but, so far, no arrest has been made.

Officers believe there are still people who may have information which could prove vital to the investigation.

Detective Sergeant Alec Francis, of Darlington police, said: "It may be that people think they have information which is insignificant, but if we put it alongside the other information we have it could prove vital.

"It's just like fitting together the pieces of a jigsaw and we are making progress."

The attack took place in Green Lane, at 5pm on Monday, May 7. The woman, who is in her thirties, was walking her dog behind her two young children when a youth, who could be as young as 14, pulled her into a bush. He then carried out a serious sexual assault.

The attacker is described as aged between 14 and 17, 5ft 8in, of stocky build with a round face and honey-blond hair. He was wearing a blue top.

The police number is (01325) 742120. People can also ring Crimestoppers on 0800 555111.
