THE BRITISH MAN WHO HAS BEATEN EBOLA: WILLIAM POOLEY BACK TO HEALTH AFTER TREATMENT IN LONDON
A two hour stand-off ensued, which ended when police shot the man several times around 1am.
The attacker was treated by ambulance staff at the scene, but pronounced dead 20 minutes later.
The woman, who reportedly knew her attacker, was not inured, but taken to hospital and treated for shock.
This comes just hours after a woman was beheaded by a man in another part of North London yesterday.
