Three schools in Yuma, Ariz., were placed on lockdown on Tuesday morning after police were called to investigate a report of a student possibly carrying a gun.
A spokeswoman for the Yuma Police Department told Yahoo News that officers responded to Rancho Viejo Elementary School at approximately 9:55 a.m. local time. That school, along with nearby Salida Del Sol Elementary School and WACOG Preschool, were placed on lockdown, she said.
Students at Salida Del Sol could be seen filing into the cafeteria with hands on their heads in front of armed police officers observing the scene.
Students at Rancho Viejo Elementary were taken by buses to a different elementary school, H.L. Suverkrup, where parents could pick up their children while police continued their investigation. The lockdown at the other schools was lifted Tuesday afternoon.
No weapons were found.
The gun threat comes amid heightened security at schools around the country after the Dec. 14 shootings at Sandy Hook Elementary School in Newtown, Conn., where 26 people—including 20 children—were killed in one of the worst school massacres in U.S. history.
The lockdown also comes on the heels of a workplace shooting in Phoenix, Ariz., on Jan. 30.
