An elementary school was placed on a partial lockdown and five homes were evacuated in San Miguel on Friday morning after an 11-year-old boy brought a World War II-era hand grenade to class for show-and-tell, according to a news release from the San Luis Obispo County Sheriff’s Office.
The student attended Almond Acres Charter Academy located on the campus of Lillian Larsen Elementary School near Mission and 17th streets in the small North County community.
“The school treated the antique hand grenade as real and called the Sheriff's Office,” just after 8:30 a.m., the statement said.
The San Luis Obispo County Bomb Task Force responded and disposed of the grenade. The pin was still in the explosive, which ultimately was ruled inert by the bomb squad, meaning it would not have exploded.

No one was hurt, and residents were allowed to return to their homes by 11 a.m.
The student, whose name was not disclosed, was not arrested and was turned over to his parents, authorities said.
