Shocking footage shows the moment a police officer's finger is partially severed after a man pulls out a hidden four-foot-long sword.
Footage captured on bodycam shows Anthony Browne, 63, suddenly lunging towards the officer after pulling the large weapon from behind his back at a property in Dagenham, east London.
The Met police officer, who was attending the home on reports of a man behaving aggressively, was hit by the sword which broke his hand and partially severed his finger.
Browne was arrested at the scene on suspicion of grievous bodily harm with intent and common assault.
He was jailed for seven years and four months after admitting to GBH at Snaresbrook Crown Court on Friday, 16 April.
The officer was taken to an east London hospital for treatment. His injuries were not life-threatening but required surgery and ongoing treatment.
Detective Chief Superintendent Stephen Clayman said: 'Anyone watching the body-worn video footage will agree that it is completely unacceptable that officers are met with extreme violence like this.

'The officer's colleagues were certainly quickly on scene when the alarm was raised.
'The fact his injuries were not life-threatening was fortunate, particularly for Browne, who could have found himself facing even more serious charges.
'I'm quite sure that this will have a lasting impact on the officer concerned who showed great courage in the face of danger.
'The dramatic escalation of violence and aggression showed by Browne highlights both the bravery and risks police officers often face, particularly in someone's own home.

'It also demonstrates that anyone who assaults an officer whilst carrying out their duty, no matter what the circumstances, will find themselves before the courts, so be warned.'
The incident happened when police attended a Dagenham address after reports of a disturbance and a man behaving aggressively at 7.40pm on 30 November last year.
Officers were confronted by Browne who started brandishing the sword and waving it in the officers' faces - Browne was tasered and detained by the officer.
