A dozen arrests were reported by Los Angeles police early Thursday after crowds took to the streets following the Dodgers' World Series win.

Video showed some people throwing objects at police in Los Angeles as sirens blared and officers told them to leave the area after the Dodgers defeated the Yankees in Game 5 in New York. A bus was set on fire, and some in the crowd were seen breaking into stores.

There were some "unruly, and at times violent and hostile celebrations," with several acts of vandalism, including the burning of a Metropolitan Transit Authority bus, Los Angeles police spokesperson Officer Drake Madison said in an email.

"Metro is disappointed and angered by the senseless act of vandalism on one of our buses following the Dodgers World Series Win earlier this evening," the transportation agency said in a statement to the Los Angeles Times.

Arrests were on charges such as failure to disperse, receiving stolen property and commercial burglary, Madison said.

There were also several instances of street takeovers downtown and police used less-lethal munitions to control several hostile and violent crowds, Madison said. In the coming days, detectives will attempt to identify those responsible for crimes, he said.

Other video showed revelers standing on top of a bus waving a Dodgers banner and people leaving a boarded-up store with sneakers. It wasn't known if anyone was hurt.

The Dodgers plan to commemorate their World Series championship Friday with a downtown parade followed by a celebration at Dodger Stadium. The team said Wednesday that, because of logistics, traffic and timing, fans won't be able to attend both events.
