Runaway horses race through central London

BBC staff member Tony Bonsignore was on the scene. He said he saw someone receiving treatment from paramedics behind a blue cloth before they were taken away in an ambulance.

Bonsignore was on a bus near Victoria Station when the incident unfolded, and said: “It’s unclear at the moment exactly what happened.

“Everything came to a standstill. Right behind us a horse hit a tour bus, and you can see where it smashed the windscreen.

“There was blood on the floor as well.”

He added: “I saw a horse that was being led away, it wasn’t clear whether that horse had been injured.

“A sort of taxi van is pretty badly smashed up on the side, again with some blood on the floor and evidence of where horses were behind it.”
