Flammable liquid caused eleven-hour M3 closure

A mystery flammable substance has been blamed for an 11-hour motorway closure this weekend.

Hampshire Police said the “potentially hazardous” substance, which was thrown from a motorway bridge on to the M3 near Winchester, on Saturday morning was flammable but not explosive.

Officers said a similar incident in the same place just a week before was also being investigated.

Winchester district commander Chief Inspector Mark Lynch said: “This is not being treated as a terrorist incident.”
