Beer cans and liquor bottles lay on the ground after fans celebrated the Philadelphia Superbowl LII victory over the New England Patriots in Philadelphia, Pennsylvania U.S. February 5, 2018.
On Sunday night and early Monday morning, crowds flipped over a car, set another vehicle on fire, took down and climbed light poles, smashed windows, scaled City Hall with a keg, and littered streets with beer cans and other debris. The Philadelphia Inquirer also reports that between "Everything is free" chants, several fans looted a gas station.
Philadelphia has now started cleaning up. Photos on social media show some of the morning-after mess.
