All Four Bombers Arrested?

LONDON, July 29 - Police in body armor, some wearing gas masks and dark ski masks and some toting automatic rifles, stormed two apartment houses in west London today and arrested three men in connection with the failed bombing attempts on London's transport network on July 21.

Shortly afterwards, the Italian interior minister in Rome said Italian police had arrested a Somali-born man with British citizenship, identified as Osman Hussain. A statement from the minister, Giuseppe Pisanu, said the man was "the fourth attacker of July 21 in London."
