Did you pay the bill? Take the hospital to small claims court as the procedure was illegal, non consensual, and not medically necessary.

I did not

Good, there's no legal standing for them to charge you. The police should be the responsible party.

If it's taken to collections, just take the hospital to small claims. You'll win. (And the hospital needs to collect from the police department that demanded the procedure.)
