Parents and students in Worcester said a teacher at Rice Square School took of his clothes and ran through the halls naked.
Franco Girardi got a frantic call from his 12-year-old son, telling him there was a naked man running around the grounds at the school.
Franco, who lives nearby, came outside and saw the man, then ran after him.
Worcester schools said the teacher was with students Tuesday afternoon when his odd behavior started and the principal put students in lockdown.
Students said they did not know what was going on, but were hearing from others who had been outside.
Dismissal was delayed and parents got a call with an update.
“The staff member became very agitated and volatile,” the message to parents said.
The teacher eventually left the school grounds and was transported to the hospital.
