London: Making a major breakthrough in the last week's bombings here, police yesterday (July 12, 2005) arrested one person, following the raids on residences in Leeds in Northern England and seized a car in Luton.

Police also believe that at least one of the suspected bombers died in Thursday's blasts that killed 52 people and injured 700 others.

"One man has been arrested in West Yorkshire and will be brought to London to be questioned," Deputy Assistant Commissioner, Peter Clarke told a press conference here.

However, Sky News television, quoting police sources, reported that all four suspected bombers died during the serial bombings in London. Three bombers died in separate Tube attacks, while another was killed in a bus blast at Tavistock Square.

The television station also said that all four suspected bombers were British citizens.

Clarke said at least three of the suspected bombers came from West Yorkshire, where police had carried out raids earlier. The home addresses of the three suspects were among the residences raided by the police.
