Remember the UK Airplane Bomb Plot? Looks like the "Ringleader" won't face criminal charges

The suspected ringleader of an al Qaeda plot to blow up passenger planes over the Atlantic won't face criminal charges for the alleged conspiracy, British authorities have revealed.

In an unexpected twist, however, Rashid Rauf may be extradited to the U.K. on an unrelated murder charge. But once in the U.K., British law prevents authorities from charging or even questioning Rauf about the alleged airliner plot.

Rauf, a British-Pakistani, denies any connection to terrorism, though he was named in British press reports and by U.K. intelligence sources as one of the key figures behind a plot to smuggle liquid explosives on board airliners bound for the United States.

It was Rauf's arrest in Pakistan in August 2006 that led police in Great Britain to call off a surveillance operation and to swoop in on an alleged al Qaeda cell whose members were said to be well-advanced with preparations for the potentially deadly operation which could have killed hundreds if successful.

The public revelation of the alleged plot led to unprecedented new security measures at airports worldwide, most of which remain in force.
