That set a nice precedent didn't it? No longer can you flit from country to country free of any pangs of guilt and enjoy the high life, despite arrest warrants out for you.
Er, except in London it seems. Even where there is a current arrest warrant out for you. And when the Police know where you are. And have you cornered.
The BBC are reporting that an Israeli General escaped capture in those very circumstances in 2005 by the simple expedient of refusing to come of the El-Al plane on the runway at Heathrow.
Due to the concern that the Police might not be able to legally board the plane (!) and due to the possibility that there may be some (illegal!) guns on the plane with his security men, the Police let the plane take-off with the General inside.
No thought of blocking the plane's taxiway until the toilets backed up and the drinks cabinet was empty and the General obeyed the law like everyone else.
Instead, as a wanted criminal, there was a subsequent apology from the then Home Secretary, Jack Straw, for the disruption that the whole unpleasant business caused the General.
So know you know the drill, when the Constabulary are in hot pursuit. Just refuse to come out and claim you have illegal guns and you're home and dry.
