Fans’ post-game fight outside Levi’s Stadium caught on video

A brutal fight after the San Francisco 49ers-Minnesota Vikings “Monday Night Football” game was caught on video, showing a man in a Vikings jersey getting repeatedly kicked and punched on the pavement in a parking lot of Levi’s Stadium.

The viral footage, which garnered more than 1 million views Tuesday before it was taken down, shows the Vikings fan on the ground being pummeled by one man wearing a black shirt and then kicked in the head by another man in a red 49ers jersey before a security guard attempted to stop the fight.

Later in the 70-second clip, people wearing 49ers gear tried to play peacemakers by holding off other fans, including a woman who walked up and kicked the Vikings supporter while he was still on his knees. The man who was beaten eventually managed to get up with the help of the security guard and walk away.

Santa Clara police are investigating, said Lt. Kurt Clarke, a department spokesman. No arrests have been made, Clarke said. Police were sent to the scene but by the time they arrived, everyone involved in the fight had vanished, he said.

“It’s very disturbing in nature and especially when someone is down on the ground and being kicked. We want to identify the suspects and obviously move this investigation forward,” he said.

Clarke said police are in touch with the man being beaten in the video and asked that witnesses with information call police at (408) 615-4849.

The team said Tuesday that it is “aware of the disturbing incident following last night’s game and are working in collaboration with the Santa Clara Police Department to investigate.” Team officials added that the “49ers and our public safety partners have a steadfast commitment to ensuring a safe and enjoyable experience for all visitors to Levi’s Stadium and unacceptable behavior such as this will not be tolerated.”

The incident comes less than a year after a man was hospitalized with a severe brain injury when he was beaten in a Levi’s Stadium restroom, a vicious attack that was also caught on video. Two men, ages 34 and 27, were arrested in the Oct. 5 attack, including one who pleaded no contest to assault charges and was sentenced to five years in prison.

Brandon Cosio posted the latest video on his Twitter and Facebook accounts, writing that the fight broke out after the Vikings fan and a 49ers fan not shown in the video were “talking smack to each other, getting into each others faces.” He said other fans told both men to stop before the Vikings fan shoved a woman into a barrier to try to get to the 49ers fan, “then at that point the 49er fan walked away from the situation and that’s when the Viking fan may have got a little cocky.”

The Vikings supporter, he said, turned around and told people, “what’s up, any of you f— want some?!”

As the Vikings backer was walking away, a fan in a black 49ers jersey tacked him, Cosio wrote, adding that no police were on the scene. That’s when Cosio started to shoot video.

The parking lot beating followed the 49ers’ 20-3 season-opening victory over Minnesota.

“Hopefully, they can show up and arrest the parties in this video,” Cosio wrote.

He praised a security guard who tried to break up the fight as a “brave man getting in the middle of that brawl.”
