A man had to be cut out of his car after a smash involving an unmarked police BMW X5 in Thornton Lodge.

Witnesses said the driver of the white BMW – a 36-year-old dad-of-two from Crosland Moor – was just pulling away from the side of the road when it was struck by a black X5 4x4 vehicle travelling at speed.

The white car was shunted across the road and into the side of a former showroom building.

Emergency services were quickly on the scene and firefighters spent half-an-hour cutting the roof off the car to release the driver. He was taken to Huddersfield Royal Infirmary but his injuries were not thought to be life-threatening.
