Last month, protest group Animal Rising issued a call for volunteers to help disrupt the event by entering the track. "One man was arrested after he ran onto the racetrack after a race had started. He was quickly removed by event security and police officers, meaning the race was not disrupted," Surrey Police said in a statement. Animal Rising shared a video of the protester being detained on Twitter, claiming that the individual was a supporter of the group. Last year's Epsom Derby was delayed after six protesters from Animal Rising, then named Animal Rebellion, entered the course and had to be removed by the police.
