DRAMATIC footage shows undercover police cars "boxing in" a car on the motorway.

Dashcam footage shows two unmarked police cars box in a Volkswagen on the M5 between J7 and J8 near Worcester last night.

The driver eventually parked up on the hard shoulder - where the car was searched by officers and a police dog.

A secret compartment containing a quantity of drugs was uncovered by the police dog, named PD Burt, during the search.

Police say it is believed the drugs were being transported via the motorway network into Gloucester.
