Olympic headquarters being built in secret for UK's elite SAS troops

London, Nov.3 (ANI): A new SAS base is under construction at the Olympics headquarters here.

It means the elite troops can combat any terrorists at next year's London Games in an instant, The Sun can reveal.

A source said last night: "It reflects the gravity of the threat."

Chinook helicopters have been in action over the capital for months ferrying special gear to the new East London headquarters.

Underground bunkers will house even more crack troops.

The SAS will have a key role to play in providing massive security at the Olympics - using "black ops" BOATS to swoop in via the Thames if terrorists attack.

A secret new riverside base being built for the Who Dares Wins heroes in East London will be home to a fleet of the high-powered rigid inflatables.

It means elite units can speed there "in seconds" using the network of waterways around the Olympic site that make it an island - with no fears about being held up in London's notorious traffic.

The plan to enlist Old Father Thames as an ally was hatched as part of a ring of steel that will be thrown around the London Games next year.

A source said last night: "All scenarios are being anticipated. London will be protected like never before - and the message is clear. If anyone is fool enough to try to endanger the public at these Games, they will be met with the swiftest retribution by the best-equipped troops of our most elite fighting units." (ANI)
