A man accused of stabbing an unarmed security guard at an Ohio hospital in the neck and abdomen has been charged with felonious assault.

Thirty-three-year-old Andrew Wallace appeared in court Wednesday and is being held on $100,000 bond. Online court records didn't indicate whether he has an attorney.

Police say Wallace stabbed a 54-year-old security guard Tuesday night while being accompanied to a psychiatric ward at Summa St. Thomas Hospital in Akron. An Akron police spokesman has said Wallace had two knives when he was taken to the hospital.

The guard underwent surgery at another hospital. He is expected to recover.

The U.S. Department of Labor's Occupational Safety and Health Administration says it is investigating the stabbing.
