FORT LAUDERDALE, Fla. -

Cell phone video shows a 16-year-old girl beaten the night police say she was gang raped.

Prosecutors say 15-year-old Patricia Montes and 16-year-old Erica Avery and three boys -- 17-year-old Dwight Henry, 18-year-old Laniel Singleton, and 19-year-old Jayvon Woolfork -- invited the victim to a house in Hollywood, where they allegedly pinned her down and began punching and kicking her. Authorities say the group refused to stop until the girl agreed to have sex with Woolfork.

"Please, please leave me alone," the victim says in the video.

Authorities say the victim refused but was eventually raped anyway, an act not depicted on the video. She suffered several broken bones in her face.

During a hearing Thursday, a judge denied bail for Singleton.
