Who called police???
Paul did.
The dude probably was a Grindr date and something happened and Paul told him to get out and the dude asked to be paid.
Dude refused to leave and asked to “see Nancy” to get paid/blackmail someone.
Paul tries to scare him off when cops show up with a hammer before he tells his story and embarrasses Paul with a prostitution solicitation charge.
Dude hits Paul over the head with a hammer and tries to run out after breaking glass door.
Cops catch him and play ‘how do we cover this up’ for 4 hrs.
