Four suspects have been arrested in connection with the beating of a Minnesota Vikings fan outside the San Francisco 49ers' stadium after Monday night's football game, Santa Clara police said.

A 70-second viral video capturing the assault on a 35-year-old man wearing a Vikings jersey helped police identify the four people suspected of kicking and punching him near the parking lot at Levi's Stadium in Santa Clara.

Three California men in their early 30s and a 17-year-old girl were arrested Thursday evening, police said. The adults were taken to the Santa Clara County jail and the girl was issued a criminal citation and released to her parents.

Police Lt. Kurt Clarke verified the video Tuesday and later identified two victims: the Vikings fan and an 18-year-old security officer. Both suffered noncritical injuries.

The video depicts several bystanders and security personnel in yellow jackets scrambling to halt the assault and tend to the Vikings fan on the pavement while others screamed "stop" and "leave him alone" and "what the hell's wrong with you guys?"

After a momentary lull, a woman came up and kicked the victim at least twice before she was pushed away.

A member of the security team helped the man to his feet, and he walked away under his own power.

Police said at least two of the adult suspects were wearing 49ers jerseys.

In a written statement Tuesday, 49ers spokesman Bob Lange said that "unacceptable behavior such as this will not be tolerated."
