A man dramatically interrupted Buckingham Palace's changing of the guards ceremony Sunday morning when he held a knife to his own throat and then wielded it at police, who tasered him into submission.
The man broke through security cordons past the large crowd at around 11:55 a.m., and was tasered by police 10 seconds later, the Daily Beast reported.
"He was not making threats to members of the public but he was challenged by police," a spokesman said, according to the Guardian. "He acted aggressively and a taser was discharged."
"There must have been about 15 police officers on foot who surrounded him once he'd been tasered," eyewitness Kevin Burrows, told BBC News. "The police saw him really quickly and were obviously cautious."
The man has been arrested and charged with causing affray.
Police at the scene said that the man was "trying to make a scene out of himself" and that there were mental health issues involved in the display, according to Channel 4.
The changing of the guards ceremony happens once every two days at Buckingham Palace, and is usually accompanied by music and watched by large crowds, according to
