“Kids would go in there to have sex, to drink alcohol. They’d push other kids in and lock themselves in with them. They’d block the drains and flood the corridor.” Another responded: “The toilets were really smelly and unpleasant. Because they were fully enclosed spaces they weren’t properly ventilated, and harder to clean.”
One teacher was worried someone could collapse unnoticed in a completely enclosed cubicle. They said: “The CCTV in the corridor was only any good retrospectively. The toilets had turn locks, so you could open them from the outside if you needed to, but you couldn’t hear through the door, couldn’t see whether there was one or two people in there, or if someone had collapsed.
“You had to check CCTV before opening. So you would have a paralytic drunk student, or one who had overdosed on prescription drugs, collapsed and you’d have to go and check the CCTV before opening the door on them. Kids would push up the ceiling tiles and hide stuff up there – drugs or whatever. Because the cubicle was fully enclosed they could do so without anyone being able to see it.”
