Several staff members were assaulted and several boys are facing charges after teens at a Littlestown youth facility could not be controlled and injured staff members with pool sticks and a metal fence post, police said.
The incident happened about 6:15 p.m. Wednesday at Hoffman Homes for Youth, 815 Orphanage Road, state police said.
Hoffman Homes for Youth is a residential psychiatric treatment facility for children who have been diagnosed with serious mental-health issues.
Mitch Snider, the facility's CEO, said no one was seriously hurt.
"We have 92 children in our care, and last night, seven teenage boys were outside their assigned residences, roaming around the campus and making verbal threats," he said.
Staffers took the "rare" step of calling state police when they couldn't get the teens under control, he said.
"When state police arrived, the boys were disrespectful and some were aggressive toward state police," Snider said. "The seven boys in question were removed by the state police, which was a decision made by the state police. They took (the youths) to a detention facility. They're going to be detained until there's a court hearing next week."
Snider said while some staff members might have suffered bumps and bruises, there were no significant injuries.
"Maybe some first aid was administered, but no one required hospital care or any significant level of medical service," he said.
Police described the incident as a riot.
At least some of the seven youths assaulted staff members with items including pool sticks and a metal fence post, according to Trooper Adam Reed, a state police spokesman.
Reed said the boys were under control when troopers arrived, and that one staff member was treated at the scene by an ambulance crew.
Snider said 90 percent of the residents have a history of aggression, which is something the staff deals with every day.
"Seven boys out of 92 -- I wouldn't consider that a riot," he said. "Based on the information I have, riot is not a word I would use."
Several of the juveniles face criminal charges, including aggravated assault, troopers said.
In Pennsylvania, even a minor assault against certain protected groups of people is automatically a felony aggravated assault. Those groups include police officers, teachers and employees of hospitals and residential homes.
Reed said police turned over the seven teens to Adams County juvenile probation officers, who placed them in a secure facility.
