A motorcyclist was killed last night in a crash which blocked part of the busy A27 for nearly five hours.

Today, traffic police issued an urgent appeal for the rider of another motorcycle to contact them.

The accident at Arundel happened just after 7pm when the biker was in collision with an articulated lorry.

A spokesman said: "A yellow motorbike was in close proximity at the time and the rider may be a witness."

The crash happened at a roundabout in The Causeway, on the outskirts of Arundel, and police say the biker died instantly.

Diversions were set up around the scene and the road was not fully re-opened until after midnight.
