Police investigating a suspected child sex ring in Oxford said last night they are speaking to more girls as the investigation continues.

Det Insp Simon Morton, right, who is leading Operation Bullfinch, said: "More girls are talking to us - but that doesn't mean more victims have come forward."

Detectives and social workers seconded from Oxfordshire County Council are continuing to talk to suspected victims and their families after the arrest of 13 men on Thursday.

Mr Morton, who was due to retire this month, is staying on to continue leading the investigation.

On Saturday, six men appeared in court accused of a number of offences, including rape, arranging the prostitution of a child, trafficking, and sexual activity with a child.

All were remanded in custody until Friday.

The seven other men arrested in the raids have been released on police bail until April 19.
