Thousands of Broncos fans celebrated Denver's Super Bowl victory over the Carolina Panthers in downtown streets, and police reported some arrests.
Fans gathered after the game Sunday night in central Denver for impromptu partying.
The crowd became unruly at times, but police for the most part watched the celebration from the sidewalk.
At one point, several dozen officers formed a united front near the 16th Street pedestrian mall to disperse a crowd trying to make its way down the street.
Police said 12 people were arrested, fewer than after the Broncos' last Super Bowl wins in 1998 and 1999.
The Denver Post reports police used pepper spray on some people, and a window on a police cruiser was shattered in an area where people tossed trash cans in the street.
