Police were trying to carry out security checks at the camp in Teteghem, near Calais, which they say is controlled by people smugglers.
Teteghem mayor Franck Dhersin described the camp as a "lawless zone".
"I am asking for the immediate dismantling of the camp, if necessary by force," he told AFP.
"The camp has always been in the hands of smugglers. It's a mafia that functions like a drug gang."
He said the smugglers that have been arrested in the region were only "small fish", and blamed the British government for failing to target their bosses whom he said were based in Britain.

Although the camp has excited huge interest in France and Britain, the numbers are tiny compared to other countries, notably Germany which is expected to receive up to a million people this year.
