There would have to be probable cause to make an arrest for the loud noise disturbance or the assault on the kids, which isn't going to happen.

Fortunately there were a couple of warrants for his arrest.

I've never been arrested by the REPs*. 

The tenants are going to file police reports in hopes of getting him arrested, but I imagine it's hell to evict someone in jail.

A police report has been filed and warrants are out for their arrest. 

I had a property manager that ended up being a crook/scammer (cost me about $10k), I had a tenant that I had screened well abandon a unit (arrested for felony), another tenant abandon a unit and has bounced rent checks (attempting to collect, owes $5k), and another tenant suddenly had to vacate due to health problems. 

I just do not want to put them out and get a ticket or worse, arrested.

I tried to offer him money but he knows that if he sticks around it would be at least 5 free months of free rents.What Im curious is if I do the steps above would the cops arrested right away after he called the cops or does he have to sue me to get me arrested?

I thought lack of utilities would help.Here once the Sheriff serves the Writ they have 24 hours to vacate, if they don't leave or are found back on the property again they will be arrested for trespassing.

Even Philly is trying to disconnect as many storm sewer connections as possible.And when I say it's illegal, I don't mean they will arrest you.
