A suspected "unexploded device" which closed part of a motorway is now believed to be a flare, say police.

A member of the public found the object under the motorway near Oldbury.

Central Motorway Police Group said a telephone assessment with Ministry of Defence bomb disposal experts suggested it was a flare and it would be disposed of.

The motorway had been closed in between junctions 1 and 2, but is now being reopened.
