No no, he says that the police let him go when the ambulance arrived. So if he spent a night in the cells, that ambulance sure took his time, and presumably the headbutt more or less killed the guy. Which would explain why he had to be "scraped up". Presumably he headbutted him so hard his head.... exploded? Unless he had some kind of medical condition.
Though I can't see the police letting him go again if he'd actually killed the guy. Plus he said it happened today.
I've re-read his post. It makes no sense to me at all now.
