A freshman Maryland men's lacrosse player was arrested and charged with sexually assaulting a sleeping woman at a Zac Brown Band concert in Virginia on Sunday, police said.

Benjamin Chisolm, 19, of Davidsonville, is accused of molesting a 49-year-old woman who had fallen asleep in the lawn area during the concert at Jiffy Lube Live pavilion in Bristow, Va. The woman told police she awoke around 8:30 p.m. to find an unknown man, later identified as Chisolm, lying beside her and touching her inappropriately. When she woke up, the suspect stood up and walked away, police said.

The woman reported the incident to officers patrolling the venue, and when Chisolm was detained later that evening for public intoxication, he was identified as the suspect in the assault, police said.

Chisolm, who scored two goals in two games last season with the Terrapins, faces aggravated sexual battery and public intoxication charges, according to online court records. He is being held without bail pending a hearing on July 17.

"We are aware of the reported incident regarding one of our student-athletes," the University of Maryland said in a statement. "The University takes these matters very seriously and will cooperate with authorities during their investigation."

Chisolm's lawyer, Christie A. Leary, did not immediately respond to a request for comment Wednesday.
