I was at Euston bus station when a bus came round (people inside and
outside looking bemused) making an external announcement that "this
bus is under attack". I think this was before ibus though.
That was a pre-ibus thing. I've heard it a couple of times.

This example is from outside London:

I think the London version sounds less panicky.

That looks like a London bus but it's going to Brighton...
