Police chiefs have condemned the violence at yesterday's Million Mask March which saw four police officers injured and several horses targeted.
Sir Bernard Hogan-Howe, Metropolitan Police Commissioner, branded those that had thrown fireworks and missiles at officers and their horses "despicable".
Embassy - one of the force's oldest horses - was startled and bolted after being targeted with a firework. The officer riding was thrown from his horse and taken to hospital with a broken wrist.
He added that some protesters had asked others to stop targeting the animals, but denied that the attacks at the 1,000+ strong march were down to the actions of a small minority.
Mr Hogan-Howe made the comments in the stables at Great Scotland Yard, while petting the horse that was injured.
