Utah authorities have arrested youth treatment facility employee after deputies say he allegedly allowed residents to choke each other as part of a game.
Authorities say 20-year-old Tuakimoana Leota was charged on Tuesday (US time) with two counts of felony child abuse.
Prosecutors say Sanpete County sheriff's deputies were called to Oxbow Academy East last Friday after a 16-year-old boy was choked until he was unconscious.
Oxbow Academy describes itself as a treatment centre for boys struggling with sexual issues.
Prosecutors accuse Leota of looking on as two residents choked each other as part of a game called "Cloud 9" or the "choking game".
