Villanova University students flooded the streets around campus to celebrate their team's 79-62 win over Michigan in the national championship game of the NCAA tournament.
As soon as the game finished Monday night, fans streamed out into the streets, cheering and chanting.
In anticipation of celebrations, light poles around the university had been greased, but that didn't stop some fans from climbing them anyway.
News helicopter video showed a small fire being set in the street and students gathered around, with some trying to jump over the flames. Students could be seen climbing trees and grabbing branches to add fuel to the fire. Police later began to move people away from the flames.
There was no immediate word of any arrests.
It was Villanova's second men's basketball national championship in three years.
When Villanova won the title in 2016, most of the more than 20 arrests were for disorderly conduct. But Radnor police Lt. Chris Flanagan said at least four people were arrested for assaulting police horses.
