A bus is set on fire and 12 arrests are made in LA as the crowd celebrates the Dodgers' World Series win Los Angeles Dodgers

After the Dodgers won the World Series, raucous crowds in Los Angeles took to the streets, set fire to a bus, broke into stores and set off fireworks. Early Thursday, police reported a dozen arrests.

Video showed people throwing objects at police in Los Angeles as sirens blared and officers asked them to leave the area after the Dodgers beat the Yankees in Game 5 in New York. It showed revelers standing on a bus waving a Dodgers banner and people running in front of a board. They stormed a Nike store with armfuls of sneakers before throwing the goods into cars parked outside.

“As we celebrate this success tonight and in the days ahead, violence will not be tolerated,” Los Angeles Mayor Karen Bass said in a statement. The mayor said Los Angeles police will be on high alert all week to protect communities and businesses in the city, which has already seen unrest following championship victories by the Lakers and Dodgers.

According to police, 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. The arrests included charges such as failure to break into, receiving stolen property and commercial burglary.

“Metro is disappointed and angered by the senseless vandalism of one of our buses following the Dodgers World Series win this evening,” the transit authority said in a statement to the Los Angeles Times.

“Less-lethal munitions were used for crowd control at several hostile and violent crowds,” an LAPD spokesman said. “Detectives will be conducting inquiries in the coming days to attempt to identify those responsible for the above crimes.”

The Dodgers plan to celebrate their World Series championship on Friday with a parade downtown followed by a celebration at Dodger Stadium. The team said Wednesday that fans will not be able to attend both events due to logistics, traffic and time constraints.
