A man has been arrested on suspicion of raping a woman at a festival in Warwickshire.
The attack at the Bulldog Bash, at Long Marston, near Stratford-upon-Avon, was reported to police early on Saturday.
A 34-year-old man from Derby was arrested and released on bail pending further inquires, police said.
Police said 14 other incidents at the four-day event were being investigated, including 11 thefts and three reports of cannabis possession.
The 24th Bulldog Bash featured rock and metal acts and a quarter-mile drag racing strip.
Warwickshire Police said it had delivered a "successful policing operation" for the event.
During the festival, which began last Thursday, a total of 400 officers and staff were deployed.
