British authorities confirmed late Friday that they found a second vehicle rigged with explosives in central London, hours after police defused a bomb planted in another car, according to dpa. The second vehicle, a blue Mercedes, had been towed after receiving a parking citation near Hyde Park. Police later inspected the car at the tow yard and safely defused the massive bomb, said Peter Clarke, head of Scotland Yard's anti-terrorism unit. "These vehicles are clearly linked," Clarke said. Like the first vehicle, a silver Mercedes found near Piccadilly Circus, the second one was found with a "considerable amount of fuel," gas canisters and a large quantity of nails, Clarke said.
