A second teenage girl was raped at Latitude Festival this weekend, just 24 hours after the first attack.
The 17-year-old was attacked in her tent early on Saturday morning. A 19-year-old man has been arrested in relation to the rape.
This follows the rape of a 19-year-old woman on Thursday night.
In the first attack, the woman had asked a group of men for directions after she lost her way. The men offered to show her the way but then attacked her.
The gang have not yet been found.
Security was heightened at the festival and the police warned women to stay in large groups.
