French police were stoned by a mob of migrants at a camp near Dunkirk after chasing suspected British people smugglers who were carrying two men in their car boot.

The driver of the UK-registered Audi A4 and his passenger reportedly fled into woods, followed by a pair who clambered out of the back of the vehicle.

The incident occurred on Sunday evening at a camp populated by 200 migrants at Grande-Synthe, a suburb of Dunkirk.

It comes following trouble at the nearby Teteghem camp (pictured above), which is also said to be controlled by British trafficking gangs

Both Teteghem and Grande-Synthe, a suburb of Dunkirk, are said to be controlled by British people smugglers who use high-powered cars to transport migrants to motorway rest areas where they are put lorries bound for the UK.

It comes days after a shoot-out blamed on crime gangs left an Iraqi man wounded in nearby Teteghem.

Both camps are said to be controlled by British people smugglers who use high-powered cars to transport migrants to motorway rest areas where they are put lorries bound for the UK.

On Sunday, the Audi sped off from a French squad car after being stopped near the Belgian border, before reportedly trying to ram its pursuer.

The car was then spotted hurtling towards at Grande Synthe, shouting ‘Police! Police!’ as a warning to the residents of the camp, before the four men disappeared into woods.

Fifteen migrants then began hurling rocks at the police car, until reinforcements arrived to help disperse the group with tear gas.

It remains unclear if the suspected British smugglers were eventually detained, but four men with links to the UK were arrested last week.

The suspected smugglers - said to be connected to British addresses and using British-registered vehicles including luxury cars – are accused of being part of a dangerous gang based at Teteghem.

A Home Office spokesman said: ‘We are working closely with the French authorities to deal with the situation in northern France.
