Two former detention officers and their supervisor were charged Monday after an investigation found inmates at the Oklahoma County jail were forced to listen to the popular children’s song, “Baby Shark,” on a loop at loud volumes for extended periods of time.

At least four inmates were subjected to the “inhuman” discipline in an attorney visitation room of the jail last November and December, according to the charge. The inmates was forced to stand the entire time, hands cuffed behind them and secured to the wall, the investigation found.

District Attorney David Prater charged them with misdemeanor counts of cruelty to a prisoner and conspiracy.
