A pair of derelict semi-detached properties were burnt to a shell in the Bierley area of Bradford as firefighters tackled the flames for two hours tonight. A hydraulic platform from Bradford fire station was called to Fallowfield Gardens just after 7.30pm. Two other pumps from Odsal joined attempts to put out the inferno which saw the roofs and ceilings between the floors cave in. It was the third time in 24 hours that Odsal were called to the street. A fire in a garden and a bedroom were put out on previous visits.
