EXCERPT
Ivan McCracken, a passenger on a Victoria line train at Warren Street station, smelled smoke and described "extremely frightened" passengers running into his carriage after a small explosion occurred in a man's rucksack.
Mr McCracken spoke to a witness who was in the carriage where the explosion happened, and said: "There was this man, a man who was a young man, who was holding or wearing a rucksack, I don't know if he was standing or sitting. The rucksack was blown open by the force of the explosion, or whatever it was. The man looked extremely dismayed, alarmed and made some exclamation, I don't know what it was.
"The train was only 15 seconds from pulling into Warren Street when this happened, so we arrived normally and there was an orderly evacuation. The escalators were working," Mr McCracken told Sky News.
Anyone want to bet on what language was used?????
Stage Coach representative saying the explosion was on the top floor of the bus. Sounds familiar.
