PHOENIX — An investigation is underway at Sierra Linda High School Wednesday after a school threat prompted a large police response.
Phoenix Police Sergeant Mayra Reeson says the situation began around 10:15 a.m. when multiple threats were discovered on social media.
Sierra Linda High School is located near 67th Avenue and Lower Buckeye Road.
Reeson says a school resource officer was alerted to the social media post which showed a countdown clock and a bench that looked like it "could be something on campus." The post also listed several other accounts which are being investigated.
As police arrived at the school, a lockdown was put in place to get all students, who were on lunch at the time, back into their classrooms.
Officials say the lockdown was out of "an abundance of caution" and officers searched the campus to make sure everyone was safe.
There were no shots fired and no injuries were reported. Police did not find any weapons on campus.
School officials sent a message to parents alerting them of the situation.
All students were released from school sometime after noon, which is around the regularly scheduled early release time.
Reeson says detectives are investigating the original account that posted the threat and says it was a newly made account.
Once a suspect is identified charges may be filed. Reeson says suspects in incidents like this face multiple felony charges and may be prosecuted.
Tolleson Union Superintendent Jeremy Calles says school will resume as normal on Thursday and Friday.
