A POLICE officer was covered in mud after a foot chase with a suspected car thief.

PC Martin Willis - who is known as "Motorway Martin" on social media site Twitter - was out on patrol in the early hours of this morning.

The officer spotted a suspected stolen vehicle on the M62 at around 3:58am.

The chase began when the driver ran off from the car and into a field.

PC Willis followed the suspect across several fields.

He was eventually caught and detained.

The chase left PC Willis covered in mud - on his boots and trousers.

He said: "You know you've had a good foot chase across fields when you look like this."
