Police arrested 118 people at Aintree Racecourse as large numbers of protesters attempted to gain entry to the track – delaying the start of the flagship Grand National. Scores of activists climbed fences at Aintree, with at least two fixing themselves to a jump using glue and lock-on devices, animal rights group Animal Rising said. The protesters breached security fences as National runners were in the parade ring, causing a delay of 12 minutes, although racegoers helped police and event organisers to stop some from reaching the track.
