This is the shocking moment a violent fight erupted between spectators at a motorcycle event - over seating.

Cynthia Martinez, 49, attended the Monster Energy AMA Supercross Championship on January 25, 2025, at Angel Stadium in Anaheim, California, and captured the incident.

A shocking video shows spectators lunging at each other and throwing punches as other attendees try to intervene.

According to Cynthia, who was sitting two rows behind, the fight broke out after a disagreement over seating.

She says the two groups argued that they had booked the same seats, which led to the fight.

Cynthia, a retiree in California, said: "The whole thing escalated quite quickly."

"The fight broke out during the opening ceremony and from what I could see, an older man and two younger men were arguing with a group sat two rows in front of us about the seating."

"The men argued that the group were sat in their seats but the group insisted that was wrong."

"That disagreement ultimately lead to a physical fight at which point I attempted to block my grandson, who's only two years old, and I decided to record in case something bad were to happen."

"Security arrived and took them all downstairs to talk."

"The original people who were sitting in the 'wrong' seats were allowed to return and it seemed they kicked the others out."
