Police tracked a driver for more than 30 miles before stopping a car and seizing a knuckle duster from a vehicle.

The Essex Police Operation Support Group tweeted that the team arrested someone on suspicion of possession of an offensive weapon and drug driving.

They had tailed a car from Brentwood to Colchester - a 36-mile journey - before asking the driver to stop.

They said the driver tested positive for cocaine at the roadside.
