A 19-year-old man accused of inappropriately touching a 49-year-old woman who fell asleep during an outdoor concert was arrested by Prince William County police on Saturday.

Benjamin Chisolm of Davidsonville, Md., was charged with aggravated sexual battery.

The victim told police that she fell asleep on the lawn during the Zac Brown Band concert at Jiffy Lube Live in Bristow. She woke up to find a man touching her, and then he walked away. She told police stationed at the concert about the assault.

Chisolm was detained for public drunkeness, and police then concluded that he was a suspect in the sexual assault. Police spokesman Jonathan Perok said Chisolm was not armed, but the charge was elevated to aggravated sexual battery because the victim was not conscious at the time of the attack.
