A 16-year-old boy has been arrested on suspicion of attempting to murder a 10-year-old girl.
The school girl is in hospital following the violent assault after Devon and Cornwall Police were called to reports the girl had been attacked in Exmouth.
A 16-year-old male from the local area has been arrested and remains in police custody.
The school girl was found by a member of the public in a distressed state near Marley Road on the evening of Thursday August 4.
Emergency services were contacted and a full police response was launched, including searches, speaking to people in the area and a forensic examination of the scene.
Police say due to the sensitivity in supporting the child, full details will take a while to become clearer.
The investigation into what happened is ongoing and police say this will involve searches of the scene and local area, house-to-house and CCTV inquiries, and further detailed forensic work.
Police would like to hear from anyone who was in the area of Marley Road and the adjacent fields late on Tuesday afternoon and may have noticed anything they feel could be relevant.
