A man has been detained and a cordon put in place after the vehicle was stopped during a routine security check at the terminal at around 10.30am.

Police have confirmed that the security incident is not linked to the ongoing search for Daniel Khalife, the fugitive who escaped prison on Wednesday.

Access to the Folkestone terminal is currently suspended and customers are advised that travel will be severely disrupted throughout the afternoon.

In a picture obtained by Sky News, vehicles can be seen queueing amid the delays.

Customers are advised to check the LeShuttle website and social media for the latest travel information.

A driver at the terminal said a member of staff told him that the area was on lockdown on Friday morning.

There would be a delay of a couple of hours minimum, he told Sky News.

Meanwhile, police are working "night and day" to recapture Khalife, Prime Minister Rishi Sunak has said.
