I've just found out why I was 50 minutes late for work this morning. I got stuck at Turnham Green on the Sadistic (sorry, District) Line, as there was a security alert at Glamoursmith (sorry, Hammersmith) and the District and Piccadilly lines were suspended. So I walked to Hammersmith hoping to pick up a Hammersmith & City Line train. But this was also suspended and police were everywhere around Hammersmith Circus. I managed to squeeze onto one of the crowded buses heading towards Shepherd's Bush, only when I arrived I found out that there were loads of fire engines and police swarming around Shepherd's Bush Green too. Fortunately the Central Line was open, so I was able to get onto to that and get into the West End.
