This is the moment police officers ram a suspected moped thief off his bike after a high speed chase through east London.

The dash-cam video shows a police car hitting the motorbike in Victoria Park as officers carried out a “tactical contact” manoeuvre in broad daylight.

The incident was filmed for a Channel 5 documentary, which followed Metropolitan Police officers as they employed new tactics to crack down on the steep rise in scooter crime across the capital.

The documentary, entitled Snatch and Grab: Moped Gangs on the Rampag", follows specialist police units that the Met have trained as Tactical Pursuit And Containment (TPAC) drivers.

The TPAC officers are able to use “tactical contact” among other measures to end a moped pursuit if necessary.

The special taskforce, dubbed Operation Venice, are filmed responding to reports of a suspect on a moped in a Hi-Vis vest.

On board cameras then film the team racing through east London streets in response to where the suspect was last spotted.

The police car is seen to entrap the biker with the help of other officer vehicles as he attempts to flee.

Cameras then capture the moment when the moped rider swerves around another car up ahead before it heads straight towards the police car.

After attempting to dodge around it an officer deliberately aims his car at the suspect, ramming him onto the bonnet, before he flies into the air.

As the biker attempts to flee an officer sprays him with a high tech water gun which is used to mark suspects with invisible liquid that can later be used to link them to the crime.

After police restrain the moped rider an officer says: “The conclusion to the pursuit was brought about by tactical contact.

"That is one of the many strands of options we have to us.

“In this case it was simply justified for the manner of riding, on a footpath, through a park, endangering peoples lives.

“We can't allow that to continue.

“If we hadn't have done this, what would he have done further down the road.”

The documentary makers said he was arrested on suspicion of five offences, failing to stop for police, suspected theft of a motor vehicle, possession of a class a drug with intent to supply, failing a roadside drug test and dangerous driving.

They do no specify whether he was subject to any further action.

Another police officer later says: “We have no desire to knock them off and cause any injury to them.

“However, that is a tactic that is available to us.

“If it is appropriate for us to use it, we will use it.”

The hardline method was rolled out across the UK last year, after incidents spiked where moped riders would violently rob people on the street as well as jewellery shops.

Scotland Yard detectives have said the tactics have helped cut moped crime by 52 per cent in a year while, in May, a London gang were jailed for a total of 68 years.

As well as garnering support from Home Secretary Sajid Javid, Prime Minister Theresa May also backed the move, saying: "Moped crime has been an issue for some time."

But the new measures also faced intense criticism when first unveiled with Shadow Home Secretary Diane Abbott saying officers are "not above the law."

They caused controversy when PC Edwin Sutton faced a disciplinary hearing for using a “dangerous” method to stop a teenager driver escaping after a suspected handbag theft.

The panel however cleared PC Sutton of any wrongdoing in May deeming the move “necessary for the apprehension of a suspected criminal.”
