Four former Vanderbilt University football players have been indicted on five counts of aggravated rape.  

The four men allegedly raped an unconscious 21-year-old woman inside Brandon Vandenburg’s room at Gillette House dormitory on June 23, according to Nashville Police. University officials noticed suspicious activity by the four players on a dorm surveillance tape. The Vanderbilt University Police Department reported the incident to Nashville's sex crimes unit on June 26.

Defensive back Brandon Banks, 19, one of the four charged was the last to surrender to Metro Police on Monday.

Receiver Jaborian "Tip" McKenzie, 19, turned himself in Saturday morning. However, McKenzie was released from Metro Jail around 1 p.m. after posting a $50,000 bond, according to a dispatcher with the Davidson County Sheriff's Office, USA Today reports.

Safety Cory Batey, 19, was apprehended at his Nashville home. He, as well as tight-end Brandon Vandenburg, 20, is now at the Metro Jail with their bond set at $350,000.

The four have also been charged with two counts of aggravated sexual battery and Vandenburg is charged with one count of tampering with evidence and one count of unlawful photography.

"Although four people are being charged at this time, the investigation is still on-going into the actions of other individuals and the role(s) they may have played in this incident," District Attorney General Torry Johnson said in a statement.

Vanderbilt dismissed the players on June 29. The university is offering the victim its services and support, Vice Chancellor Beth Fortune reportedly said on Friday.
