A 13-year-old boy had his leg amputated Tuesday after being thrown to the ground by a school employee in September. The unnamed student was attending the Edgewood Student Services Center in Columbus, Georgia when the incident took place. Edgewood is an alternative educational program for students who have been removed from their previous schools.

Police Lieutenant Consuelo Askew filed a report Sept. 12 after he was called to the school to respond to an altercation. “Mr. Bryant Mosley (behavioral specialist) advised me that he had to physically restrain a student,” the report read. The boy’s attorney said he was attempting to leave the classroom to call his mother when Mosley slammed him to the ground twice, the Atlanta Journal-Constitution reported.

Mosley was specifically trained in the MindSet curriculum, a system of preventing and managing aggressive behavior, the Muscogee County School District said. He was not a district employee but was a contract worker provided by a behavioral services company.

“It is our understanding that there were issues concerning the safety of the child and others in the room,” said school district’s Director of Communications Valerie Fuller in a Tuesday statement. “Physical restraint is allowed in Georgia public schools and educational programs in those situations in which the student is an immediate danger to himself or others and the student is not responsive to less intensive behavioral interventions including verbal directives or de-escalation techniques.” It’s unclear if Mosley tried any other techniques before tackling the boy.

Mosley has not yet been charged with a crime, WALB reported, though he is no longer working for the school district. The boy will remain at Children’s Healthcare of Egleston to recover from the amputation and undergo physical therapy, his attorney said.

The story bears similarities to a video that emerged in April of a San Antonio school resource officer body-slamming a 12-year-old girl in a classroom, knocking her unconscious.
