ARSONISTS are thought to have star- ted a blaze which ripped through offi- ces at a derelict warehouse.

Fire crews from Cleckheaton and Batley were joined by crews from Dewsbury and Mirfield at the building on Roberttown Lane in Liversedge, early yesterday.

A spokesman said: "The fire had spread through four rooms in the offices. It took a good hour to get under control and we were at the scene for four hours damping down."
