Diman Regional Vocational Technical High School on Wednesday morning was briefly locked down after police said a caller claimed to be having a mental health crisis and was in a school bathroom with an assault rifle and a bomb.

Fall River police later said the incident appeared to be "a hoax call."

All students were dismissed at 12:30 p.m. after the lockdown was lifted and parents were allowed to take their children home.

The school first notified parents via the ParentSquare app of a lockdown around 10:15 a.m. Parents flooded the scene around Locust Street and Stonehaven Road. Police blocked the area around the school with vehicles during the incident, and a State Police helicopter circled the scene.
