I separated my tenant from beating his wife to a pulp in March of this year.  After she ran into my house and my room and dove into the closet. He still was beating her. After pulling him off he fought me for 9 minutes. He ended up hitting me in the back of the skull with a Big Mag flashlight. I went to hospital later that day and had a CT scan and was released. I had a camera in my house record the whole thing. Easy for police.  He was caught and sent to jail where he still is. 
I sent him to the hospital too.! for the record.
