Large crowds were cleared by police in riot gear, after the Red Sox won their second World Series title in four years.

An unruly crowd flipped a pickup truck to its side near Fenway Park and at least one car fire was reported. Young people sprayed each other with beer and some climbed street signs or utility poles.

Boston police spokeswoman Elaine Driscoll said 37 arrests were made in the city, mostly for disorderly conduct.

No serious injuries were reported.

The Red Sox won the game 4-3, touching off celebrations around New England.

On Sunday, hundreds of police officers took positions on foot, bicycle and horseback around Fenway, hoping to discourage fans from congregating around the ballpark.
