(Reuters) - Tennessee state and local police set up a perimeter around a youth detention center on Wednesday night after about 20 boys were discovered outside their rooms without permission following a larger break-out from the facility earlier in the week.
As of 2:30 a.m. on Thursday, no injuries or arrests had been reported at the Woodland Hills Youth Development Center in Nashville and all of the teens were contained within the police perimeter, the Tennessee Department of Children's Services said.
Additional staff were on duty and social workers were talking to the youth to try to convince them to return to their rooms, the department said. A police helicopter was circling overhead.
"It's still kind of fluid right now," department spokesman Rob Johnson said, declining to provide additional details.
A group of 32 boys escaped from the facility on Monday. Most were either apprehended by police or turned themselves in, but six boys remained at large as of Thursday morning.
