SAN FRANCISCO (AP) — San Francisco officials are taking tougher measures to prevent potential fan violence on Super Bowl Sunday when the 49ers battle the Baltimore Ravens in New Orleans.

With the Niners’ sixth appearance in the big game more than a week away on Feb. 3, San Francisco police said they will be monitoring crowds and bars at multiple hotspots across the city. More than 400 officers will be on duty, triple the number on a normal Sunday.
