They were arrested for "suspicion of Aggravated Assault" and released on bond. Story says they lived in a city, so there may be an ordinance violation for the ordnance?

...within city limits.
...within X feet of an inhabited building/dwelling.
might be the most common ordinances violated.
It is definitely time to shut down the lockdown when people get so bored this is all they can think of to do....
