Thieves who stole five supercars worth almost £500,000 from a Norfolk airfield posted footage of their audacious heist online.

The gang took the cars - including a Lamborghini and a Porsche - in an overnight raid at Tibenham Airfield where they were being kept for driving experience days.

They filmed themselves removing the keys to the vehicles from a cupboard in a secure building on the airfield and, hours later, recorded footage of themselves sitting in two of the cars in a London street.The thieves filmed themselves stealing keys from a locked cupboard at Tibenham airfield and later in the Lamborghini and the Mercedes in a street, thought to be in Barking, London, with the caption 'Yktv' (you know the vibe) (Image: Supplied)

Car Chase Heroes, which owns the cars, said there were security personnel at the site at the time of the raid, in the early hours of Saturday, and people sleeping nearby.

However, the gang was able to get into the building on the airfield, near Diss, and drive off in the cars without being detected.

Villagers say they heard the vehicles being driven through Tibenham at around 4am on Saturday.

Other witnesses have since claimed that they saw the cars - a red Lamborghini Huracan, a bronze Audi R8, a yellow and black Mercedes AMG GT, a white and blue VW Golf and a white Porsche Cayman - being driven in convoy southwards down the A11 and M11 a short while later.

There were also reports of the Lamborghini and another sports car being driven 'erratically' on the A505 near Baldock, in Hertfordshire.

The cars, which are worth a combined £450,000, are all distinctive. The Mercedes has an unusual orange and black paint job and the VW is decorated in the livery of the Sale Sharks rugby team.

Referencing the Hollywood car theft film starring Nicolas Cage, Nik Coleman, a spokesman for Car Chase Heroes, said: "I don’t know if they were gone in 60 seconds or in six minutes. But realistically, if you have stolen a supercar you’re not going to hang around."

He added: “The footage just popped up on social media. Lots of people saw it and passed it along. I don’t know what to say. It’s extraordinary.

"From my point of view, it's extraordinary that you'd steal a car and then post about it online. It seems astonishing. It’s all a bit of a mystery, a car heist.”

Car Chase Heroes had to cancel their planned driving experience days at the weekend because they could not use the other cars without their keys.

Mr Coleman said: “There was a selection of 35 cars there, so why they chose these five in particular we’re only going to ever hear in a courtroom one day.

“They stole the keys for all 35 cars so that’s why we couldn’t go forward. Backup keys are held at a number of secure locations in the UK and they do need to be gathered together.”

Would-be guests were emailed at 8.31am on Saturday about the cancellation.

The company said it would organise another event for people who missed out.

"About 900 people have been left disappointed as we were expecting about 300 spectators a day," Mr Coleman added.

Police say the incident happened between midnight and 4am and anyone who may have witnessed the incident is asked to get in touch quoting crime reference 36/69420/24.

Tibenham Airfield was a major base for US bombers during the Second World War. It is currently used by the Norfolk Gliding Club, as well as for driving events.
