WALNUT — The sheriff’s bomb squad went to Mt. San Antonio College Thursday and determined an artillery shell brought to the campus was an inert display piece, authorities said.
Deputies were alerted about 4:37 p.m. that someone had brought what appeared to be a 40mm artillery shell to Mt. SAC, 1100 N. Grand Ave., Los Angeles County sheriff’s Lt. John Saleeby said.
Deputies evacuated the building and called for the bomb squad, the lieutenant said.
The bomb squad arrived at building 60 — listen on the campus website as a science building — and determined that the shell contained no explosives and was merely a display piece, the lieutenant said.
Officials sounded the all-clear about 6 p.m.
The reason the shell was brought to the school and who brought were not available, Saleeby said, however it appeared no crime had been committed.
