Two teenage brothers from Valdosta accused of participating in the sexual assault of another teen in Rome have been granted bail.

Robert Darshawn Sharp, 17, of Valdosta was charged with aggravated sexual battery. Jamel Marshawn Sharp, 17, of Valdosta was charged with being party to the crime of aggravated sexual battery.

Both Sharp brothers were released on a combined $30,000 bail Thursday.

The brothers are being represented by Valdosta attorney Roy Copeland.

Dallas Kendrick Brown, 17, of Lawrenceville and Kenny Thomson Mason, 17, of Valdosta were also charged with being party to the crime of aggravated sexual battery.

All four of the teenagers were also charged with simple battery.

Brown and Mason were released on a $20,000 bail on Wednesday night. Brown is being represented by defense attorney Vic Reynolds of Rome. Mason is being represented by

Steve Lanier of Rome.

The young men were in town for a wrestling camp hosted by Team Georgia at Shorter University. The incident is alleged to have occurred July 8 in school dorms leased by the camp.

The victim told a wrestling coach that he and a group of boys had been playing when the boys held him down and Mason hit him. He said that group of boys left, and another group came in and held down his legs while he was assaulted with a toothbrush, according to the police incident report.

Detective Jeff Richerson with the Rome Police Department is investigating the case. He said the boys knew each other prior to the assault, but most likely some of them had just met while attending the wrestling camp.

July 12 Update: Four teens arrested over the weekend on aggravated sexual battery charges remain in the Floyd County Jail. Bond has been denied for all four suspects.
