Reports now that a 2nd car containing bomb materials has been found.

Police in London’s bustling nightclub and theater district on Friday defused a car bomb that could have killed hundreds after an ambulance crew spotted smoke coming from a Mercedes filled with a lethal mix of gasoline, propane and nails. Hours later, police confirmed a second explosives-rigged car was found nearby.

Clarke said Friday evening that the second car—another Mercedes—was originally parked illegally on nearby Cockspur Street, but had been towed from the West End to an impound lot near Hyde Park.

“The vehicle was found to contain very similar materials to those that had been found in the first car,” he said. “There was a considerable amount of fuel and gas canisters. As in the first vehicle, there was also a quantity of nails. This like the first device was potentially viable.”
