Horrifying footage: Machete-wielding maniac terrorizing an entire neighbourhood

Horrifying footage shows weapon-wielding killer Nicholas Salvador, 25, nicknamed  Fat Nick strolling through a north London suburb during a violent 45-minute rampage in which he beheaded a great-grandmother.

Met Police helicopter camera captured the man smashing down fence, breaking into back garden with machete in hand and the police officers saying 'the lady is dead, she's been decapitated'

In the footage, the killer is seen storming through back gardens in Edmonton, north London, after attacking 82-year-old Italian café owner Palmira Silva with a machete. Before the ferocious attack on the elderly woman, bare-chested Salvador  had beheaded two cats, just three doors away from where the elderly woman lived

At one point, the 25-year-old strode towards a driver who was sitting in his car and threatened him with the weapon, forcing him to flee from the scene.
