Britain Arrests 4 Suspected of Ties to 2005 Transit Bombings - New York Times: "LEEDS, England, May 9 — The British police on Wednesday arrested three men and the widow of a suicide bomber involved in the terrorist attack on the London transit system in 2005 on suspicion that they helped in the atrocity, which killed 56 people, including the 4 bombers.
Three of the early morning detentions, the second round of arrests in six weeks in connection with the attack, were in the West Yorkshire region of Britain where three of the four suicide bombers lived, and the other in Birmingham, in the West Midlands region.
The arrests suggested that after a long period of investigation with little early success, the police were beginning to piece together how the plot worked and who else, aside from the four suicide bombers, was responsible.
In a stern message last month, Peter Clarke, the chief of counterterrorism at Scotland Yard, said that his investigators would soon catch up with others who he said were aware of the planning of the attack.
The arrests on Wednesday appeared to bear out Mr. Clarke’s remarks.
For a long time, it seemed that the authorities would be unable to charge anyone with the transit attacks, which took the worst peacetime casualty toll in Britain’s history. But the latest arrests, together with the apprehension of three men in late March, are changing the presumption that the bombers took the secrets of their plan with them.
Now, the organization behind the attack — both in Britain and in Pakistan, where two of the suicide bombers had traveled — could be publicized at a trial. It is unlikely, however, that those arrested Wednesday masterminded the plot, analysts said. "
