The widow of July 7th suicide bomber Mohammed Sidique Khan was among four people arrested in a series of anti-terror raids in Britain today.
Five houses in West Yorkshire and two flats in Birmingham were cordoned off and searched by police. Unarmed police carried out the raids which are connected to the 2005 London bombings in which 52 people were killed.
The three men and one woman were arrested just after 7am today and taken to a central London police station to be interviewed by anti-terror officers.
They are being held on suspicion of the commission, preparation, or instigation of acts of terrorism under the Terrorism Act 2000.
There has been criticism of both the police and the security services over their handling of the July 7th attacks. It emerged last week that links were missed between two of the suicide bombers and those recently convicted for the fertiliser bomb plot.
MI5 observed July 7th ringleader Khan and sidekick Tanweer meeting the fertiliser bomb plotter Omar Khyam on numerous occasions in 2004 — a year before they detonated their bombs.
It was also claimed that Khan came to the attention of counter-terrorist police just five months before the bombings. Police took down details of his mobile number and an address in Batley which were given to the manager of a garage in Leeds when he borrowed a courtesy car, The Guardianclaimed.
He also gave his mother-in-law's address in Dewsbury, to which MI5 had tailed him less than a year before. The security service has been accused of not properly following up the clues or passing on details to West Yorkshire Police.
