A blaze at a used-car sales garage this morning is being treated as arson.

The fire damaged more than a dozen of the 60-plus vehicles parked inside the Fleet Motor Company building in East Parade, Keighley.

Police scenes-of-crime officers and fire investigators are at the scene.

Fire crews from Keighley, Bingley and Haworth were called out to tackle the blaze, at 3.30am.

They cut through roller shutter doors to gain entry to the single-storey building and used thermal imaging cameras to help locate the fire, which was towards the back of the premises.

Steve Spencer, a watch manager with Keighley fire service, told us: “The building was heavily smoke logged which, together with the density of vehicles parked up in there, made locating and reaching the seat of the fire difficult.”

Crews wearing breathing apparatus used two water jets to bring the blaze under control.

A police spokesman said it was too early to speculate about exactly how the fire started, but he confirmed it was being treated as suspicious. There were signs someone had broken in.

The area outside the building has become synonymous in recent months with car clamping, with several motorists complaining about their treatment at the hands of the clampers.
