A dozen people were arrested Sunday during the revelry in the Mission District after the San Francisco 49ers' NFC Championship victory, police said Monday.

One person was arrested for assault with a deadly weapon, one on an outstanding warrant and one for driving under the influence. Nine people were arrested for public intoxication, police spokesman Officer Gordon Shyy said.

Crowds spilled into the streets following the 49ers' 28-24 win over the Atlanta Falcons on Sunday, briefly taking over part of Mission Street near Silver Avenue, Shyy said.

However, there were no reports of vandalism like that seen in October, when rowdy crowds damaged storefronts along several blocks in the Mission after the San Francisco Giants won the World Series, Shyy said.

He said police are already planning for the Super Bowl on Feb. 3, when the 49ers will face the Baltimore Ravens in New Orleans.
