A Keighley community has been left "disturbed and disappointed" following the latest in a string of fires at a former school in the town.

Firefighters today tackled a blaze at Branshaw School, which was targeted by arsonists two months ago.

Keighley West councillor Adrian Farley took to Twitter to say: "Very disturbed and disappointed to hear about a further (possible) arson attack on the former Branshaw School site in the early hours."

Crews from Keighley, Bingley and Shipley stations were called to the Nashville Street site at 3.50am.

A spokesman for the West Yorkshire fire service said a 40-metre by 60-metre building was 100 per cent ablaze when crews arrived on scene. The fire did not spread elsewhere and no-one was injured, said the spokesman.

The building was in the process of being demolished, and the spokesman said the demolition company had been contacted to get the building brought down as soon as possible.

In October, the former special school, which closed in April 2010, was hit by arsonists. Keighley West councillor Brian Morris said at the time the school "had been left to go to wrack and ruin".
