The latest threat comes after a similar one was made against Southeast Polk High School, Sunday. On Monday morning, in an unrelated incident, a man went on a random shooting spree in Pleasant Hill that hospitalized two.
Police arrested Pete Polson, 32, in relation to that incident. He faces 11 charges including attempted murder.
Police say Wednesday’s threat was made on Yik Yak at about 1:30 a.m. It didn’t mention anything about the schools in the area but did mention gunfire targeting Pleasant Hill police officers.
As a precaution, officers checked students’ backpacks at Southeast Polk High School as they entered school Wednesday morning.
Troopers with Polk County and the Iowa State Patrol will have an increased presence in the community Wednesday because of the threat. Pleasant Hill officers have contacted the administrators of the Yik Yak app.
