Barry Baker, 59, who lived alone, dialed 911 saying that he thought he was having a heart attack. An ambulance was sent to his house while a controller kept him talking on the line.

By the time the ambulance arrived at the house in Patcham, Brighton, Baker had collapsed, but the telephone line was still open and was being recorded.

It is alleged that staff in the control center heard the two medics making disparaging comments about the state of the house.

A police source, who asked not to be named, said that the medics were then heard discussing Baker and saying “words to the effect that he was not worth saving."
