Several items of contraband, including prescription drugs, a stun device and apparent marijuana, were recovered from McMinn County High School on Monday when the school was locked down as part of planned operation, authorities said.
Among the items confiscated were a large amount of tobacco products, prescription and non-prescription medications, an electric stun device, a can of pepper spray and a small amount of what appeared to be marijuana, Sheriff Joe Guy said in a news release.
Before the lockdown began about 10 a.m., students were given an "amnesty" period. Boxes were placed in the classrooms and students were advised that any items voluntarily disclosed would not result in charges.
The operation was not the result of any specific threat or incident at the school, Guy said.
