(LAPEER) -- Officials say a security officer hired to help protect a Michigan charter school left an unloaded handgun unattended in a school bathroom. Chatfield School Director Matt Young says that the security officer "made a breach in security protocol" in leaving the gun "for a few moments" on Monday. Young says no children at the school in Lapeer were in contact with the gun or put in danger. The school for kindergarten through eighth grade recently hired the security officer, who is retired from the Lapeer County Sheriff's Department, to help strengthen security. The county prosecutor's office says a criminal charge isn't expected, since no one was harmed.
