A caretaker could face disciplinary action after he locked two teenage girls in a school courtyard overnight.
The worker has now been suspended from his position at Whalley Range High School in Manchester.
The 15 and 16-year-old girls were trapped in an outdoor courtyard for 12 hours overnight after going into school for extra maths tuition on a Saturday morning in March.
Staff left for the day unaware that the teenagers were still on the premises.
The girls had no food or water with them, and could not call for help as one of them had left her mobile in the classroom, and the other's was out of battery.
The Manchester Evening News says they were reported missing by their parents before eventually managing to pile benches on top of each other to climb to the top of a nearby building and jump to safety the following day.
The police and paramedics were called to the school when one girl returned with her parents to speak to staff on Sunday morning. She was uninjured apart from a pain in her hand, but was said to have been left 'shaken' by the incident.
The headteacher at the all girls' school, Patsy Kane, said they had launched an investigation and reviewed their out of hours procedures.
"Although both families reported their daughters missing to the police later that evening, no contact was made with the school until the following morning," she said. "By this time the pupils had managed to get themselves out of the building by climbing onto the low level roof of the quad and had gone home."
