A second car bomb has been found.

LONDON — Police thwarted a car bomb attack Friday in London’s bustling nightclub and theater district, defusing a crude explosive device made of gasoline, propane gas and nails after an ambulance crew spotted smoke coming from a green Mercedes outside a nightclub. Hours later, police confirmed that a second car bomb was found in the center of the city.

Update: Looks like there was a hero-cop on the scene.
