(L-R) Naweed Ali, Khobaib Hussain & Mohibur Rahman were found guilty of preparing acts of terrorism
The trio were arrested last year after security services bugged one of the men’s cars, as well as uncovering a pipe bomb and a meat cleaver hidden in a JD Sports bag.
Convicted terrorists Naweed 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.
The officer, who gave evidence anonymously, linked Hussain with the JD Sports bag, saying he carried a similar one on earlier visits to the fake firm’s depot.
Vincent was cross-examined over 12 days and repeatedly rejected the allegations against him.
The court also heard that he described the claims in a private message as “the usual bollox”.
Two of the defendants came from Stoke-on-Trent while other two were neighbours in the Sparkhill area of Birmingham.
However, the jury at the Old Bailey found all three guilty after deliberating for 22 hours.
The jury continued to deliberate on the fourth defendant Tahir Aziz, 38, but later found him guilty of preparing terrorist acts.
