The moment a Household Cavalry horse threw its rider to the ground in a separate incident on the same day horses ran loose through central London was seen in footage captured by the London City Walks YouTube channel. At Horse Guards Parade, a soldier was seen lying on the ground after a horse became spooked on Wednesday (24 April). "Oh a trooper has been thrown, oh good lord," the man filming says. It came on the same day five horses rampaged through central London, two of which ran more than five miles and suffered serious injuries but are still alive.
