My question involves criminal law for the state of: Florida
So my brother and his ex GF had a spat, she was punching him and burning him with a cigarette and also clawed part of his ribs. To get out the situation he had to push her away and ran out of her apartment (she let him in and she started going through his phone while he was asleep and awoke him to pummel him) a few days later she files a restraint order and files battery charges. The police came by yesterday and were looking to "talk to him" and he was not home. My father a retired police office, asked them if they had an arrest warrant, in which they replied no. They told my father today he had a felony charge for "false imprisonment" when he turns himself in he gets charged wtih " burglary and strangulation" The exgf's testimony on teh restraint order was torn apart by my brother's lawyer and shown to be inconsistent. But yet they came to arrest him.
This does not add up to me, there was no arrest warrant, they said there was "probable cause", no prosecutor assigned to this case, and if this is a felony. Please someone make sense of all this
