Around 11:40 a.m., students were evacuated from Watertown High School for the second time today. Superintendent Terry N. Fralick said the cause may have come from new gas monitors installed in the building.
Weve been having trouble with some over-sensitive gas monitors, he said. Its a chronic problem.
Mr. Fralick said the Watertown Fire Department is assessing whether there is a leak to worry about.
