Parents throw about 100 children out on to the streets of Oxfordshire every year, according a report by the Children's Society.

The research shows that one in five are physically or sexually abused after being thrown out of their homes.

The Children's Society is campaigning for local authorities to make the country safer for young runaways.

Chief executive Bob Reitemeier said: "These are society's disposable children, thrown away or fleeing family violence.

"We're rallying supporters to join the campaign and challenge local authorities to pass our 'Safe and Sound' test. The aim is to make sure these children have somewhere safe to stay and someone sound to turn to."

Lesley Dewhurst, director of the Oxford Night Shelter, said: "A disproportionate number of our clients have come from broken homes, have been in care or have had a split from their family."

The Children's Society said few of the 15,000 under-16s who are thrown out each year are reported missing.

One teenager said: "I was badly beaten all the time and told to leave in the next week or my bags would be packed and I'd be chucked out."

Some are forced to beg, steal, deal drugs or become involved in prostitution because they are wary of approaching social services or the police for help.

Mr Reitemeier said: "We need to offer family support so these problems can be resolved. And we must give these children somewhere safe to stay if family breakdowns reach crisis point."

Phil Hodgson, Oxfordshire County Council's head of social care for children, said: "We work with families to see if it is appropriate and safe for children to return home, and to help overcome the difficulties at home. Where children cannot and should not return to the families for their own safety, Oxfordshire does and will take the necessary action."
