Two Army horses that bolted through central London in full-time veterinary care

The two military horses that were seen galloping through central London's streets last month remain under full-time professional vet care and observation, the PA news agency understands.

Quaker, a Cavalry black, and a grey called Vida bolted after being spooked by builders moving rubble while they were on an extended exercise with five other horses and six soldiers from the Household Cavalry.

According to an Army source, the two animals continue to make good progress and, of the other horses that bolted, two are back on duty and three are recuperating in fields.

The horses belonged to the Household Cavalry Mounted Regiment, which is based at Hyde Park Barracks in Knightsbridge, the ceremonial face of the Household Cavalry which conducts regular mounted state and public duties.

None of the horses will be taking part in the King's Birthday Parade – Trooping the Colour – on 15 June, according to the source.

Four service personnel were thrown from their horses as the animals got loose. The horses smashed into vehicles, including a double-decker bus, and caused a number of injuries.

Ambulance crews treated four people in three separate incidents in Buckingham Palace Road, Belgrave Square and at the junction of Chancery Lane and Fleet Street, in the space of 10 minutes.

The drama began near Buckingham Palace Road where witnesses saw a serviceman thrown from his horse and one of the loose animals crashed into a taxi waiting outside the Clermont Hotel, shattering windows.

Two horses were then seen running in the road near Aldwych, one of which appeared to be covered in blood, which the Army said was "consistent with lacerations".

Jordan Pettitt, 26, who works for PA, said the grey horse was "vividly" stained red with blood and he heard a black horse collide with a taxi.

The animals were later seen near the Limehouse Tunnel before they were recaptured by City of London Police and taken away to be assessed by Army vets.

At the time of the incident, Lieutenant Colonel Matt Woodward, the Commanding Officer of the Household Cavalry Mounted Regiment, said in a video update that three injured soldiers were being treated in hospital for non-life-threatening injuries and the horses were also safe, undergoing veterinary care back in barracks.
