Police shut down a stretch of the M6 motorway when someone on a Megabus got panicked by some smoke and reported strange goings on - smoke and liquids.

The horror. The horror!

"Given the nature of the report we responded swiftly and proportionately, treating the information as credible and extremely seriously. Our utmost priority was the safety and security of those people on the coach and those travelling on the motorway."
