According to swedish newspaper "Dagens Nyheter" (equivalent to The Times) , the pilot in question was supposed to fly at 0830 local time but was picked up by the airport police. Breath-test showed 0.2 promille. A blood test was also taken, and its result was reported to take a couple of days.
BA spokesman was quoted to say (freely translated) "we take this very seriously" and also that they were going to "gather as much info as possible".
Passangers had to wait for about three hours, until BA had a replacement pilot.
