BBC News - M6 Toll coach stopped by armed police
I opened my thermos, poured the water into my pot and this happened.
A police source told BBC Radio WM a passenger was seen pouring a liquid into a box, which then started smoking.
The 48 passengers on the Megabus Preston to London service were led off the coach and forced to sit apart in a cordon on the opposite carriageway.
