San Francisco is cleaning up after some revellers celebrating the Giants' World Series victory turned rowdy.

KTVU-TV reports a public transit bus was set on fire, a vehicle was flipped over, and the windows of several businesses and vehicles were broken as fans took to the streets following the Giants win Sunday night.

Fans also lit bonfires, fuelling them with couches, signs and newspaper racks. Firefighters had to be escorted in by riot police to fight some of the fires.

Police made arrests, although the exact number was unknown. A call to a police spokesman by The Associated Press on Monday morning wasn't immediately returned.
