This video comes from a Madrid bullfight that went horribly wrong. As you’ll see, the bull jumped into the crowd, trampling spectators and leaving 40 people injured before the bull was eventually controlled (and then killed). As this article about the incident explains:
The incident occurred Wednesday at the Tafalla arena in the northern region of Navarra. The event, attended by about 3,500 spectators, involved mostly young people trying to get a bull to charge at them so they could dodge it. Unlike standard bullfights, the bulls are not killed in these events.
The bull had already attempted to jump into the stands twice. After damaging a horn, he was about to be returned to the corral and replaced with another bull when he tried a third time and succeeded.
