(LAPEER) -- Officials say a security officer who left his gun unattended in a Lapeer charter school's restroom will keep his job. According to Chatfield School Director Matt Young, the school reviewed the incident and has decided the unnamed officer "is a good fit for the position." But Young says the K-8 school has revised its security procedures and added additional protocols. They include installing "a lock box in a male staff restroom for our security officer to secure his weapon in while he uses that restroom." The county prosecutor's office has said a criminal charge isn't necessary, since no one was harmed. Chatfield recently hired the officer to help strengthen security. He's retired from the Lapeer County Sheriff's Department.
