The unsuspecting tourist squeals and runs towards her friends, as the crowd watches on with their mouths ajar.
The group inspects her wound and one man uses a cotton bud to treat the bite mark.
But her condition worsens and she appears to fade in and out of consciousness before falling to the ground completely.
In a separate video, the woman is being fanned by her friends as she lies against the gate.
In an unprecedented move, the King’s Guard is seen using his sword to signal to the cameraman before saying: ‘Can you go and get the police officer?’
As officers tend to the injured woman, tourists continue to crowd around the King’s Guard and his horse – with some still trying to pet and stroke the unsettled animal.
Despite being on duty, the King’s Guards continue to have dangerous run-ins with members of the public.
Clear signage around the area warns of the horses kicking or biting but tourists still eagerly approach – often at their own peril.
