Video Shows Violent Attack After 49ers-Vikings NFL Game

— -- Police are searching for the men seen in video pummeling a rival fan following Monday’s San Francisco 49ers game against the Minnesota Vikings.

The video shows a swarm of fans in 49ers jerseys punching and kicking a Vikings fan following the 49ers’ 20-3 win. The Vikings fan can be seen on his hands and knees, trying to break free. At one point, a security official tried to intervene, but fists continued to fly.

The person who posted the video claimed that the Vikings fan instigated the attack. The victim is reportedly recovering from his injuries.

Santa Clara Police were dispatched to the scene, but the assailants fled before the officers arrived, police said.

“It’s disturbing, it’s shocking, and we’ve put investigators on it to fast-track this case and identify these folks, and bring them to justice,” Santa Clara Police Lt. Kurt Clarke said.

The 49ers said in a statement that they’re working with police to find those responsible. “Unacceptable behavior such as this will not be tolerated,” the team said.

The situation follows other high-profile brawls involving fans. Last year, an assault in a bathroom at the 49ers’ home field, Levi’s Stadium, left a victim partially paralyzed. Additionally, Bryan Stow was in a coma for nine months after being attacked by two men on baseball’s opening day at Dodger Stadium in 2011.

The NFL has condemned fan violence, with its code of conduct prohibiting physical harassment of opposing teams’ fans. The league has also encouraged teams to put ejected fans through a four-hour online fan code of conduct class.
