(DAILYMAIL) — Holding a blade to his own throat, this was the moment a knifeman brought chaos to the Changing of the Guard ceremony at Buckingham Palace yesterday.

Talhat Rehman, 54, of Harrow, has been charged with possessing a bladed weapon in public and affray, and will appear at Westminster Magistrates Court today.

The middle-aged man walked through crowds of tourists clutching two large kitchen knives before police surrounded him and used a Taser stun gun to disarm him.

As a policeman shouted a warning call of ‘Taser, Taser, Taser’ to his colleagues, the knifeman allegedly lunged forward, brandishing a six-inch blade in a series of swipes, before falling to the floor as he was stunned by the electrical charge.
