WATCH: London Police Officer Goes Crazy Smashes Car Window & Saws It Open With A Knife

A police officer has been caught on camera smashing a car windscreen and sawing it open with a knife in a furious attempt to get a driver out of his vehicle.

The dramatic video shows the officer shouting at the driver to open the door while standing outside the man’s car in Camden, north London, at around 5pm on Friday.

When the man refused, the constable tried to force the side window open three times with his hands.

He can then be seen hitting the windscreen with his truncheon in the footage which is being investigated by police.

The driver, who captured the action at Weedington Road on his mobile, refuses to cooperate and insists he ‘has a licence and insurance’.

The officer shouts at the man: ‘You’re not allowed to drive it’ and tells him to ‘get out of the car’.

The footage, which has been shared by a former member of the music group So Solid Crew, has gone viral on Twitter with more than 40,000 views.

The driver tells the officer during the footage: ‘You’re smashing this for no reason. Look, look what they are doing to my car.’

He also says: ‘What’s the problem officer. Why ain’t I allowed to drive the car?’

But the officer continues in his bid to remove him from the car and alleges the man is ‘disqualified’ and ‘not allowed to drive’.

Once the windscreen is smashed the officer pulls out what appears to be a pen knife and begins cutting the section of the screen out.

This is enough for the driver who jumps out of the other door and is quickly surrounded by another officer who is seen earlier standing by a police vehicle.

The driver repeats what he had said earlier and says he is ‘not TJ’.

He tells the officers he is filming and says: ‘Do you know what you just done?’ to which the officer replies: ‘I’ve done absolutely nothing, I just need to know who you are.’

The driver asks why the officer had smashed the car windscreen to which the policeman says: ‘I can’t see who you are in that car’.

Before the footage ends the driver tells the officer his name is ‘Leon’, to which the officer responds: ‘Leon that’s it. I’ve not seen you in a long time fella.’

The driver has since said the incident was a case of ‘mistaken identity’, describing the officer’s actions as ‘a completely unlawful act’.

Leon Fontana, a 25-year-old mechanic, said he was the driver and the person who filmed the footage.

He said the incident took place on Friday evening in the Gospel Oak area of north London when he had gone out on an errand for his mother.

He said it was a case of ‘mistaken identity’, describing what happened as ‘a completely unlawful act’.

Mr. Fontana, who said he spent the evening in hospital due to getting glass in his eyes, said it was ‘complete madness’ and that he is ‘still in shock’.

He said: ‘Every time he smashed the glass, fragments of glass were just ricocheting in my face.’

The Metropolitan Police said it is ‘aware of footage circulating on social media of an incident involving two uniformed officers in Camden’, adding that the incident took place at Weedington Road, north-west London, at around 5pm on Friday.

In a statement, the Met said: ‘The footage will now be subject to an investigation by officers from the Directorate of Professional Standards (DPS).’

The police force said on Saturday evening: ‘As soon as the MPS was made aware of the footage, the DPS was contacted immediately. The individual who uploaded the footage has been contacted by DPS officers.

‘As this matter is in its early stages, the officers have not been suspended or placed on restricted duties. No-one was arrested during the incident.’

Mr. Fontana said he is not sure when his car will be fixed and described the whole incident as ‘very stressful’, adding: ‘I can’t believe it to be honest. I can’t believe it. I’m still in shock.’

The video, which could not be independently verified, has been shared on Twitter and Instagram where the officer’s actions have been described as ‘mindless vandalism and intimidation’.
