Four men have been arrested by detectives investigating the gang rape of a 17-year-old girl in a secluded nature spot.
The men - aged 19, 20, and two aged 33 - were held last night in connection with the attack last Friday evening.
The two 33-year-olds were bailed to August 3, while the two other suspects remained in police custody, Thames Valley Police said.
The attack took place in woods near the Jubilee River in Slough, Berkshire, after the victim had met a group of men earlier in the day.
The victim started talking with one of the men and walked with him along the high street, stopping at an off licence.
The pair then walked along Spackmans Way before moving on to a footpath and into some woods near the Jubilee River.
Four other men, who were part of the earlier group, arrived at the location in a small silver car. The girl was then raped by "several of the men", police said.
