VANCOUVER, Wash., Dec. 17 (UPI) -- A high school in Vancouver, Wash., was evacuated Tuesday after a note threatening a bomb and three suspicious devices were found on campus, police said.
A police bomb squad determined two of the three devices were not explosive, and the third was destroyed, The Columbian reported.
Evergreen High School was emptied of its 2,700 students after an on-site police officer found a note in a restroom warning there as a bomb on the premises. The students were first sent to the school's stadium, then brought inside a nearby middle school because of subfreezing temperatures. They were sent home by 3 p.m.
One of the suspicious devices was found in a garbage can and another outside near some portable classrooms. The third -- the one that was destroyed using a robot and high-pressure water -- was a black backpack found at the football field after the students left.
Kim Kapp, a spokeswoman for the Vancouver Police Department, said authorities were especially cautious because of a bank bombing last Friday in Woodburn, Ore., that claimed the lives of two police officers and critically injured a third.
"Obviously it weighs heavily on our minds," Kapp said.
