AN 18-year-old girl has been arrested on suspicion of perverting the course of justice after police called off their search for an alleged rapist.

Detectives had launched a major inquiry after an 18-year-old girl claimed she was raped in the grounds of a village primary school in Burwell, near Newmarket.

But a police spokesman said last night they were no longer looking for anybody in connection with the alleged attack.

He added: "An 18 year-old girl from Burwell has been arrested on suspicion of perverting the course of justice and has been released on police bail."

Police in Cambridgeshire had launched a full-scale manhunt after a girl claimed she was raped in the grounds of Burwell Village College in the early hours of Thursday morning.

She claimed she had been walking home after a night out in Newmarket. She said she had got a taxi with a male friend from Newmarket, and was dropped off in Burwell and proceeded to walk home alone.

According to the girl, as she went through the school grounds a man pushed her against the fence and then chased her through a grassy area before raping her.

As soon as they were alerted to the alleged attack, police spent hours trying to trace the attacker.

More than 10 police officers carried out door-to-door enquiries in the Burwell area and a police helicopter was also scrambled to try and locate the attacker.

The girl was also taken to Addenbrooke's Hospital in Cambridge for treatment.

The arrested teenager was questioned by detectives at Parkside Police Station in Cambridge yesterday before released on police bail. She is due to return on August 12.
