I would be calling my attorney for legal advice, and how to proceed.
Violating a court order, has its own consequences. You cannot protect your kids from a jail cell.
Can you get a copy of the police report Today?
Police sharing disturbing news with you regarding this matter, and then just drop the ball and walk away, that isn’t ok, how are you to protect your kids without their continued support?
Call your lawyer, best I can offer.
