Four men were arrested by British authorities in connection with the gang rape of a 17-year-old girl near London on Friday.

A 19-year-old, 20-year-old and two 33-year-olds were detained Sunday night. The two youngest suspects were in custody as of late Monday morning local time while the two 33-year-olds were bailed to Aug. 3, according to Sky News.

The girl was gang raped in a wooded area by the Jubilee River in Slough, a town in Berkshire, about 20 miles from London. Thames Valley police said the victim was talking with the group of men and walked with one in the group to a liquor store before eventually walking into woods near the Jubilee River. That’s when four other men in the group met up with the pair, and several of the men gang raped her, the Guardian reported.

Despite the arrests, British police urged anyone with information about the gang rape to come forward with information, indicating that more men were believed to be involved or witnessed the attack.

"I would like to speak to anyone who may have seen these men in the Chalvey area last night, around early evening, and who may have seen them driving around in a small silver car,” said Thames Valley Police Detective Inspector Nicola Hurdley, according to Sky News. "All the men are described as being Asian."
