The police were called to the M1 near to junction five by motorists concerned about the way the man was driving.

A total of six cars and the police helicopter chased the man up the motorway and onto the A414, before he stopped at the junction with London Road in St Albans.

The driver was arrested on suspicion of taking the vehicle without the owner’s consent and dangerous driving.

There were no injuries or crashes with other vehicles.
