Hello, OP here! I work in a mental health and learning disability care home, so when I say resident I mean in the sense they live there. He's normally absolutely lovely, very quiet and calm, however something clearly snapped that day. I'll never know whether it was on purpose or not unfortunately! It was only a small torch (flashlight) but it was dropped about 10 ft directly onto my temple which was incredible aim if nothing else. It's not a locked unit so he's allowed stuff like that, however I did "misplace" it after the incident. A trip to the hospital emergency department after my shift proved there's no long lasting damage other than a mild concussion. After that though I've kept my distance from him... just in case!
