My Patient Did What?

I work as a registrar in the ER, and while I was photocopying my patient's paperwork from the PD there was suddenly screaming. I turn around and he's fighting a nurse and two techs. He managed to remove his 4-point restraints. He then leaps past them and runs down the nearby hallway.

He apparently stripped naked as he was running away and escaped the hospital and ran across the street and was immediately picked up by the cops who were literally just leaving after having dropped him off and taken to the local psych ward. (The cops had originally dropped him off because they found him on a local street throwing himself at cars).

Edit: This fine gentleman has been back twice this past week, but not under police custody.
I've been on light duty due to injury so working the front desk where people walk in instead of roving the halls with a COW.
The first time he walked in right past me straight to vitals, and the second time he came in, and flopped down on my desk mumbling and muttering and refusing to tell me what was going on. The tech of the day came in to help sort him out and get him in a wheelchair. The first day he left after he went through triage, I'm not sure about the second.
I really hope at some point he's able to get the proper help he needs.
Oh, and both times he was clothed and stayed clothed.
