Vietnamese escaped through the tunnel

Four immigrants who fled a detention camp via a network of pipes are being hunted by police. Four illegal immigrants have fled a detention centre in ‘Great Escape’-style, using maps found on the internet.

The Vietnamese immigrants, who faced deportation, used old World War II tunnels built under the Oakington Immigration Reception Centre in Longstanton, Cambridgeshire.

Sources said the group of young men, whose exact ages are unknown, cut through razor wire fences after crawling through a metal service duct similar to those used for air conditioning.
They are believed to have stumbled upon the details of the network on the internet, using the IT room onsite, The Sun reported. The tunnels linked old war bunkers and went outside the site’s fences.

A spokesman for the UK Border and Immigration Agency said: "We are currently working to recapture four detainees.
"This is an ongoing operation so we cannot comment further. "We believe that these men do not pose a threat to the public."

The men, who escaped the overnight lock-up between Thursday and Friday, were being detained for offences of cannabis production and possessing forged documents.

The centre, a former RAF base, can hold up to 352 men and opened in 2000.
