San Francisco police say at least five people were arrested when celebrations following the Giants' World Series victory turned rowdy.
Revelers were seen jumping on cars, rocking buses and tossing toilet paper Monday night after the Giants captured their first World Series title since they moved from New York more than a half century ago.
Video from KTVU-TV showed crowds swarming and attacking the occupants of a car in the city's Mission District before police intervened. A window at the Dugout Store at AT&T Park was also broken, and several fires were started nearby.
San Francisco Mayor Gavin Newsom says the vast majority of people celebrated peacefully and police did a good job of keeping order.
