Violating the restraining order is a mandatory arrest. 

If he was arrested, but not convicted he could be released and back in your unit.

They are arresting people in lots of places.Can't he set up some band equipment and work out inside (or in the garage or outside)?

I would tell the guy tenant that his wife can't stay there as there's a restraining order and she'll be arrested if the landlord's mother or niece call the police on her for violating the restraining order. 

The police said they have warrants to arrest for stolen goods.

Now I post right in the property description FICO of 675 minimum, no bankruptcy, liens or judgements for 10 years, no arrests in past 5 years, income to rent of 3:1, references etc. 

However, this tenant is refusing to leave per the Virginia governor's stay at home order but to complicate things, he threatened to call police if I showed up on my rental property and did any showings of any room at the townhouse and claims he called the local police department and they said I would be cited/possibly arrested for violating a stay at home order.Does any of what he claims even sound right?

Her son broke back in after they moved out, set off big fireworks in the unit, he and his friends got arrested for underage drinking and causing a disturbance. 

They're not going to arrest him but it'd be nice to plop that paper down in front of the judge when you sue the guy.

Come to find out, she was arrested for ill use of a weapon and was in jail.
