*Throngs of people arrived in downtown Los Angeles this afternoon as law enforcement officials were on alert for potential looting or violence after Game 7 of the NBA Finals between the Los Angeles Lakers and Boston Celtics, reports the LA Times.

Officials plan to close Figueroa Street between Olympic and Pico boulevards. More street closures are also possible.

Metro bus routes in the area are being rerouted, and it’s possible that light-rail and subway service could be interrupted at the 7th/Metro Center station and other stops “depending on conditions in the area,” according to a Metro press release.

The Los Angeles County Sheriff’s Department said it might also shut down Whittier Boulevard in East L.A. if large crowds gather after the game.

Law enforcement agencies will also increase their presence along Crenshaw Boulevard in South L.A.

LAPD Chief Charlie Beck said “extraordinary measures will be in place” to prevent unrest.

Meanwhile, in Boston, the same precautions are being taken:

Authorities are deploying hundreds of state troopers and local police officers around Boston for crowd control as the Celtics take on the Lakers in Los Angeles in Game 7 of the NBA finals needing a win for an unprecedented 18th championship, reports the Associated Press.

Boston police are closing some streets and ordering bars not to take in new customers at the end of the third quarter of Thursday night’s game.

Some of the streets being closed are in and around the Celtics’ home court of TD Garden and around Fenway Park, where the Boston Red Sox have a home game against the Arizona Diamondbacks.

State police also will have more than 100 troopers from various units staged in the city to assist Boston police, including canine, mounted, tactical and helicopter units.

Some Boston sports celebrations in the past decade have ended in tragedy, including three deaths since 2004.
