A Manchester fire chief said it was "too early" to say what led to firefighter Stephen Hunt's death as he tackled a blaze in the city yesterday.
Steve McGuirk, county fire officer for Greater Manchester Fire and Rescue Service, said:
It doesn't look like a building collapse or that he fell through any floors. The early indications are an absolutely massive, ferocious and sudden build up of heat.
But where that came from and what caused that we have got absolutely no idea at this stage. That's really the purpose of the investigation that we are now engaged in.
