Eight men were arrested during "terrorism" raids in London on 30 March. A ninth, a 27-year-old, was arrested two days later in Crawley, West Sussex, and later released. Two of the men, a 21-year-old and a 19-year-old, were released on 8 April after questioning at Paddington Green Station. A large sack of fertiliser, said to be suitable for the manufacture of explosives, was recovered by police during the operation. No other bomb components were found.
The arrests received huge media attention, accompanied in many cases by background articles claiming that police had "foiled" a series of bomb plots since September 11 2001. None of these plots have been proven in court to have actually existed.
Six of the men arrested - one of them just 17 years old - appeared at the Old Bailey on 15 April charged with conspiring to cause an explosion. Three of them faced an additional charge of possessing fertiliser for a purpose connected with an act of terrorism.
