7/7 bombings: Pak-bound suspects held

All were arrested on suspicion of committing, preparing or instigating acts of terrorism. The force said the suspects were being taken to a central London police station for questioning. The houses which being searched were all in Beeston, a working-class area of Leeds that was home to three of the July 7 bombers.

Officers were also searching an apartment and a business in east London. Two people were arrested in Britain in 2005 in connection with the July 7 bombings. One was released without charge, while the other were charged with wasting police time.

The July 7 attacks on three subway trains and a double-decker bus killed 52 people and wounded more than 700. Three of the bombers 8212; Mohammed Sidique Khan 30, Shehzad Tanweer 22, and Hasib Hussain 18 8212; were British-born men of Pakistani descent who grew up in the ethnically mixed Leeds area, about 200 miles north of London. The fourth, Germaine Lindsay 19, was born in Jamaica and raised in Britain.

The fact that seemingly unremarkable British youths could become suicide bombers caused soul-searching across Britain and raised fears of a threat from homegrown terrorists. The police investigation seemed to have stalled, and an official account of the attacks published last year concluded that it8217;s likely that the plotters who inspired and prepared the bombers were still at large. The Metropolitan Police said they remained 8220;determined to follow the evidence wherever it takes us to identify any other person who may have been involved, in any way, in the terrorist attacks.8221;
