An estate agent who lost his job after a drink driving arrest has been jailed for four years after he tried to stab a policeman.
Swansea Crown Court heard that Tony Buttigieg was raging after losing his £42,800 job as a manager.
Worried neighbours called police after he banged on their doors, saying that someone was after him.
As the shocking video footage – taken on a body-worn camera by another officer – shows, PC Rhydian Jones was lunged at as Buttigieg was tasered.
The policeman was wearing a stab vest and was unhurt, but in a victim impact statement he said he believed Buttigieg was going to kill him.
When Buttigieg was arrested last October, he was found to have taken cocaine.
The court heard that in the three months before the attack, he had lost his job and his relationship had broken down.
The court heard he was suffering a psychotic episode at the time of the attack.
Buttigieg, of Newport, pleaded not guilty to attempted murder, but guilty to attempted grievous bodily harm.
Judge Paul Thomas told him: “Knives can and frequently do kill.”
The video is testament to the astonishing bravery of police going about their daily duties.
