Among the alleged fan transgressions: throwing beer bottles and cans at police horses.
The Chicago Blackhawks won their second Stanley Cup in four years by defeating the Boston Bruins Monday night. The game ended around 10 p.m. Chicago time, allowing locals to get in several hours of celebration.
Although 2010's celebrations served as a spiritual cleansing of sorts for Blackhawks fans, last night's managed to be similarly robust and, predictably, not everyone was able to stay within the law. Among the alleged transgressions: throwing beer bottles and cans at police horses; throwing glass bottles at police vehicles; climbing on top of traffic poles, cars, and bus shelters. Chicago police said that by sunrise, a total of 23 arrests had been made and 21 tickets issued.
The official victory parade will take place in downtown Chicago on Friday. Below, the best videos we've found from last night's "unofficial" celebrations:
Some fans were carried around on what were originally barricades put up to prevent street crowding.
Others came equipped with their own fireworks.
Barricades on both sides of one Wrigleyville street came down thanks to enthusiastic crowds despite police efforts.
After the sidewalk barricades collapsed, a man was arrested while police horses moved in to contain the scrum.
Downtown, a more car-centric celebration took place.
Back in the Northside, one man brought out his convincingly realistic Stanley Cup replica.
And lastly, one man forced a car to slow down before jumping on it, only to then jump onto another car moving in the opposite direction.
