On March 30, 2004 British Metropolitan and local police launched Operation Crevice, a raid to uncover suspected Pakistani terrorists operating in England. The suspects were accused of acting on orders from Al Qaeda to create and detonate fertilizer bombs in several busy London centers.

After being delayed six months, the Crevice Conspiracy trial began in March of 2006. The trial lasted over a year and became the most expensive in British history, costing over 50 million British pounds.

"This was not a group of youthful idealists. They were trained, dedicated, ruthless terrorists who were obviously planning to carry out an attack against the British public."

"At the time it was the largest counter terrorism operation ever seen in the UK. The success was achieved through close co-operation and sharing of intelligence between the UK, the USA, Canada and Pakistan."
