The emergency services were called to Saint Thomas Street North at around 4pm on Saturday.

On Saturday, the police said a 42-year-old woman died at the scene. Neighbours identified the woman as Sadia although this is still to be confirmed by the authorities.

Meanwhile a teenage girl, who is understood to be the daughter, was treated for serious injuries.

On Monday, the police revealed she remains in hospital in a critical condition.

An investigation started following the fire with an appeal for information from those in the area at the time. Neighbours are still to be allowed back into their homes.

Detective Chief Inspector Andrew Naismith, of GMP’s Major Incident Team said: "An investigation has been launched to try to establish the circumstances that very tragically led to this woman’s death and to the serious injury of a teenage girl.

"Everyone at GMP sends their condolences to the loved ones of the woman who sadly died. The family of the victim are now being supported by specialist officers and have been kept updated throughout. They are also assisting us with our enquiries.

"You may notice an increase of police visibility in the area in the coming days, if you have any concerns, please speak to one of our uniformed officers who will be patrolling the nearby areas.

"We are still working with partner agencies to get those residents who have been displaced back into their homes as safely and soon as possible. A number of those residents have been provided with alternative accommodation by Oldham Council."
