THREE boys arrested by police over a serious sex attack on a Sheffield schoolgirl have been released on bail.
Detectives interviewed the trio following an allegation a girl had been assaulted in woodland near Acres Hill Lane, Darnall, on Wednesday afternoon.
Police arrested the boys in a move involving the South Yorkshire Police helicopter, which was called in to monitor activity in Darnall from the air when officers were alerted to the reported attack.
The boys were held overnight on Tuesday and kept in custody all Wednesday while detectives looked into the allegation.
Specialist officers interviewed the boys and the girl because of their young ages.
The boys have been allowed home while police carry out more enquiries.
