A 14-year-old boy and his parents were questioned by sheriff’s detectives Monday after the boy brought a plastic BB gun to Lemon Grove Academy Middle School last week, officials said. Other students saw the boy with a replica firearm in his backpack on Friday, but it wasn’t reported to school staff members until Monday, according to a Sheriff’s Office statement. School administrators contacted deputies after they were notified that the replica firearm had been brought to the school. Detectives contacted the boy and his parents and seized the BB gun, the statement said. The Sheriff’s Office said there were no known threats against Lemon Grove Academy Middle School. “The safety of our school children is a priority for the Sheriff’s Office,” the statement said. “We take all threats seriously. We want to remind students that if they hear any threats or even potential violence, they should and can always approach school staff or call the anonymous Student Speaking Out Hotline at 888-580-8477.”
