Bull riding can be a dangerous sport, but people usually don’t think they are at risk for a bull attack when they are merely watching an event. However, this was not the case for 40 people who were injured at the Tafalla bullring in Spain on Wednesday.

In the Navara region of Spain, A Bull jumped into the crowd to trample and gore unsuspecting fans of the event. The event taking place was called the “recortadores” where people try and get as close to the bull as possible without getting injured or gored. As the bull was being removed from the competition, it jumped over a wall and enter the bleachers, where it ran rampant.

After the bull was subdued, he was put down. You can see a video of the disturbing event below.
