Old Rochester Regional Junior High and High Schools was put on lockdown for a little more than an hour on Thursday after being told of a possible gunman on campus.

The threat, made via the Internet, came through a call center in another state, according to Mattapoisett Police Captain Anthony Days.

The Massachusetts State Police issued a statement saying that at least 32 schools in the state received threats today, though Days said he did not know if ORR received the same threat as other schools.

Police from all three towns responded to the school around noon, blocking off the entrances on Route 6 and stationing officers at the doors of the building while others inspected the interior of the schools. Police officers with high-powered firearms could be seen standing outside several doors.

A number of officers were already at the school for an anti-drunk driving presentation when the threat came in.

A number of people stopped along Route 6, including David Lizotte and his wife who have one child at the junior high and one at the high school.

"As soon as it happened, I got a text from [my daughter]. We wanted to come down right away," he said. "They were told to stay in place. They're under the desks."

Around 1 p.m., the all clear was given and officers were told they could leave their posts at the school entrances.

At a press conference held at 4 p.m. on Thursday, Principal Mike Devoll said the new ALICE  safety protocol was put into effect. ALICE (Alert, Lockdown, Inform, Counter, Evacuate) is a more active approach to a lockdown situation and allows for more information to be disseminated in a building, such as where an intruder is located. The additional communication could allow staff and students to escape through a window or exit if they know a threat is on the other side of the building.

Devoll said the last major incident at the school was 10 years ago when someone wrote a threat on a bathroom wall. Then, students were evacuated to Tabor Academy.

After the lockdown was lifted, school continued as usual, and parents were notified of the incident. Teachers met for a debrief after school.

Devoll said more information would go out to parents on Thursday and that Friday would be a normal school day, though there will be extra support and police presence.

"In instances like this we encourage families to send their kids to school," Devoll said. "We will begin [Friday] morning with a debriefing over the loud speakers so [students] understand what happened today and where they can go if they have any questions or concerns."
