Eighteen Canyon County sheriff’s deputies were dispatched to two Middleton schools Tuesday morning, when a second-grader reported seeing a classmate carrying a weapon onto a school bus.

Two schools were placed on lockdown. The weapon turned out to be a toy gun, found inside Middleton Heights Elementary School.

“These types of situations require an immediate and overwhelming law enforcement response,” Sheriff Kieran Donahue said in a statement released after the incident. “That just shows the urgency with which we handle these matters.”

The student was immediately suspended, the Idaho Statesman reported Tuesday afternoon.
