Detective Inspector Alan Lyford, of Staffordshire Police, said: “This is a complex ongoing investigation and, while we appreciate there is a demand for answers, our primary aim is to understand exactly what happened in this tragic fire.” 

DI Lyford said that, following preliminary findings from fire investigators, he had taken the decision to rule out several rumours which had spread locally. 

“We do not believe that a boiler defect was responsible and we can confirm there is no truth in rumours that cannabis was being grown at the property and may have been a cause.” 

“We’d again like to thank people for their patience, but kindly ask that people do not speculate as such comments can be misleading to an investigation as well as causing upset.” 

A 24-year-old woman and a 28-year-old man arrested on suspicion of manslaughter by gross negligence following the fire have been bailed while enquiries continue. 
The man and woman arrested are living at an address out of the area.
