British police say they are examining suspicious material found in a north London apartment connected to at least one of the suspects in last week's failed transit bombings.
Investigators Tuesday said they found a large quantity of possibly explosive material in the house. The apartment, which police raided Monday, has been dubbed by some British newspapers as a 'bomb factory.'
Earlier, police released the names of two of the suspects, one a naturalized British citizen from Eritrea and one a Somali living in the country legally.
No one was injured in the July 21 attacks, and officials say the four would-be bombers are most likely hiding in Britain.
Two weeks before, on July 7, 56 people, including four suicide bombers, died when explosions ripped through three subway trains and a bus.
