FRANTIC mother Tracey Cobb has spoken of the fears she harbours for her14-year-old tearaway son after he moved in with a teenage mum-of-two.

The 35-year-old Melksham woman says her teenage son Luke is living with an 18-year-old woman in Bowerhill and refuses to go back on a SocialServices care and education placement in Telford.

Miss Cobb, of Methuen Avenue, said police and Wiltshire Social Servicesare powerless to act and she believes Luke will quickly descend into a life of crime and drugs. The worried mum believes her son is having a sexual relationship withthe young woman but police cannot act without evidence.

Troublesome Luke was put into care when his desperate mother could no longer cope with his violence at home.

The teenager repeatedly attacked his younger sister and refused to go toschool and has been in and out of foster placements for most of his life.

But Mrs Cobb is frightened his crimes will escalate and is desperate for help.

She said: "It is disgusting a 14-year-old boy is allowed to move in with an 18-year-old girl with two children.

"I have been told nothing can be done. I know my son and he will not goback to that placement. If it was a 14-year-old girl I'm sure something would be done.

"I was told Luke is not at risk and is streetwise. He is 14. I was not even told where he was staying and I am his mother his legal guardian."

Luke came home from Telford for a short break at home two weeks ago butrefused to return to his placement.

Mrs Cobb said her son then moved into a house in Bowerhill with the older woman. On Saturday Mrs Cobb saw the couple in Bowerhill, which sparked off a huge street row.

She said: "I saw the woman and I told her I was Luke's mother and asked her why she wanted a 14-year-old boy. How can he support her?

"I was shouting and not being calm. Luke appeared and demanded his stuff and I told him to go back to his placement.

"He came into the car and I believe he was going to attack me. My friend pulled him off.

"I think he will end up behind bars.

"It is not easy to say I don't care what he does. I am thinking how can he do this to me but a mother's love never dies."

Mrs Cobb, who has three other children, lives with her partner Robin.

She believes no one is willing to help save her tearaway son.

John Matthews, assistant director of Wiltshire social services, said it was a difficult situation. He said: "Mrs Cobb is Luke's legal guardian. There is nothing the police can do unless a crime is being committed. The county council does not have parental control. We do provide a placement for Luke where he receives care and it's our view that he will return there.

"Police informed us about Luke's whereabouts the same time as they informed Mrs Cobb."
