Nearly a week after St. Patrick's Day, Sparks police are looking into a holiday "bar brawl" that may have involved four Washoe-County deputies.
Iinvestigators say the deputies were off-duty, when they went to O-Ski's pub, on Victorian Avenue.
At some point, at least one of the deputies reportedly got into a fight with a group of men, in the bar's parking lot.
Three people were hurt, including an officer, and another man who suffered serious head injuries.
No charges have been filed and no disciplinary action has been taken.
Sparks police are hoping more witnesses will come forward, to help them figure out what happened.
