Man tasered outside Buckingham Palace

A man was in police custody last night after being tasered outside Buckingham Palace while shouting and holding a knife to his own neck.

The man, thought to be in his 50s, was seen ranting and also pressing another 15cm blade to his chest, while holding a set of beads.

As a policeman shot him with the Taser, he lunged at the officer, taking a series of swipes before the electrical charge knocked him to the ground.
