Hall-Dale Middle and High School buildings in Farmingdale were evacuated briefly Wednesday morning after a report of a bomb threat written on a middle school boys bathroom wall, police said.

Regional School Unit 2 officials had students and most of the staff moved to the elementary school as a precaution while the buildings were searched. Police received the report shortly after 10 a.m.

The students returned to their classrooms after searches of the buildings were complete and no suspicious items were found, said Lt. Chris Read, of the Kennebec County Sheriff’s Office.

Superintendent Bill Zima said the students were given food while at Hall-Dale Elementary and returned to the middle and high school campuses before 1 p.m.

The evacuation came amid heightened concern over school safety nationwide in the wake of a deadly shooting at a school in Parkland, Florida.

“We acted with caution to ensure the safety of our students,” Zima said.

A Maine State Police police dog team was also at the scene assisting in the search of the building, Read said.

Read said the investigation is ongoing and the school administration will determine whether any charges will be filed. Zima said he wouldn’t comment because it’s an open investigation.

No other information will be released, Read said.
