Members of a terrorist cell who dubbed themselves the “Three Musketeers” have been found guilty of plotting a Lee Rigby-style attack following a partly-secret trial plagued by accusations of police corruption.

The gang, from the West Midlands, were poised to strike police and military targets on British soil, the Old Bailey heard.

They were arrested in August last year after MI5 bugged the car of Naweed Ali and uncovered a pipe bomb and meat cleaver hidden in a JD Sports bag.

Convicted terrorists Ali, 29, Khobaib Hussain, 25, and Mohibur Rahman, 33, had claimed the incriminating evidence was planted by an undercover officer known as Vincent, who posed as the boss of a fake firm called Hero Couriers.

But they were unanimously found guilty after the jury deliberated for 22 hours.

The jury was still deliberating on the fourth defendant Tahir Aziz, 38, who denies the charge of preparing acts of terrorism.
