The violent confrontation went down in Quebec on New Year's Eve, when cops were called to a home after neighbors complained there was a party raging inside, in violation of COVID guidelines.

Cops say the homeowner lied to them and claimed there were only 2 people inside the house. The noise inside told a different story, as well as the number of cars that were parked outside.

All hell breaks loose, as people inside the home start fighting the cops. The homeowner claimed cops used excessive force, and also tore into the P.D. because one cop was not wearing a mask. A spokesperson for the department says yeah, the cop wasn't wearing one because someone had just hit the guy on the head and his mask flew off.

Cops say it's highly likely everyone inside the home will get slapped with a big fine. The Dept. is also considering assault charges against some of the people inside.

Cops in Quebec City issued 46 tickets for public health violations.
