A British driver zipping through northern France was caught going 265kph during a clandestine car rally across Europe.
The driver was one of six given tickets for going at least 180kph on the A26, known as the "British Motorway", which links Calais with Reims.
The Voix du Nord newspaper, which first reported the racers, showed a picture of one of the stopped vehicles bearing logos for the Modball Rally, an annual event whose motto is "Drive all day... Party all night!"
Organisers did not immediately respond to requests for comment, but the Modball website says this year's rally began Sunday in London en route to Paris, the first leg of the rally.
The website says drivers are not supposed to race, but that does not stop dozens from competing to be the first to arrive at the daily destinations during the week-long event.
Four of the drivers stopped on Sunday were temporarily prohibited from driving in France, though the Voix du Nord said they were allowed to continue on their way after their teammates agreed to drive and they had paid a €750 (Dh3,260) fine.
This year's Modball involves 180 modified vehicles heading from London to Paris and then on to Lyon, Monaco, Venice and Vienna, where the rally is set to wrap up on Friday.
Race fees cost between £3,000 to £4,000 (Dh14,500 to Dh19,500) and gives participants access to lavish parties. Organisers insist they do not encourage speeding.
"We focus on the events each night and keep driving time down to ensure safe journeys between cities," they write on their Facebook page.
