Knifeman interrupting Changing the Guard tasered outside Buckingham Palace

London, Feb 4: A crazy man has been taken into custody after being tasered outside Buckingham Palace while shouting and holding a knife to his own neck.

Hundreds of people had gathered to watch Changing the Guard when the man, believed to be in his 50s, appeared from behind security barriers.

He began screaming incoherently, as he held one large green-handled knife to his neck and another pointed at his stomach, the Daily Mirror reports.

Suddenly the man appeared to confront a member of Scotland Yard’s elite SO14 royal protection squad who tried to calm him.

The officer, carrying a holstered sidearm and wearing a bullet-proof vest, calmly took out his Taser and fired it into the man’s midriff.

As the knifeman fell to the ground, just yards from the main palace gates, he was immediately pounced on by police officers, and later disarmed and cuffed by a number of other officers.

Some bystanders fled in panic and others who had been standing close to the scene were moved away by police on horseback.

Throughout the drama the palace band played on without missing a beat.

A 45-second clip of the incident has also gone viral after being posted on YouTube.

“Crazy man with a knife to his throat just stopped the changing of the guard at Buckingham Palace. I got some wicked pics and a video,” Grant Shepherd, who captured the footage, tweeted.

Scotland Yard confirmed that a man was being questioned after being found in possession of two knives near the centre gates of the palace.

According to the report, it is understood that the man will also be undergoing psychiatric treatment.

The Queen and Prince Philip were at Sandringham at the time and Buckingham Palace refused to comment.

The Taser looks like a gun but, instead of bullets, fires an electric shock into its victims, who will suffer involuntary muscle contractions and be immediately incapacitated, it added. (ANI)
