Five Household Cavalry horses, including one soaked with blood, ran loose in central London after they were 'spooked by the noise of builders moving concrete'.
Five people, including three soldiers riding on the horses, were injured in three separate incidents during the six-mile rampage on Wednesday that lasted two hours.
This morning, six soldiers and seven horses from the Life Guards were on an extended Watering Order, an exercise to keep up the fitness of animals not involved in the public-facing King's Life Guard duties.
As they passed through Wilton Crescent in Belgravia at 8.40am, it is believed builders were using a travelator with concrete when some of the concrete came off and hit the floor, causing a noise.
This is thought to have caused the horses to spook. Five bolted and two remained in place. Four soldiers were unseated and three were injured and taken to hospital. None are in a life-threatening condition.
However, onlookers said one of the Household Cavalry soldiers was left 'screaming in pain' after he was thrown from his horse when it struck a car by the Clermont Hotel on Buckingham Palace Road, Victoria.
The horses rampaged for six miles before they were finally caught in Limehouse, east London. The injured horses saw a vet and all of the animals are now back at the Army's camp.
