A man and a woman have died following a fatal house fire in Lancashire.

Police have launched an investigation following the blaze at a house in Peter Street, Blackpool, in the early hours of this morning.

A woman in her 20s was found dead at the scene while a man, also in his 20s, was later pronounced dead at Blackpool Victoria Hospital.

Two children have also been taken to hospital for treatment. Police have described one of them as being in a “very poorly condition.”

Police have since confirmed the four people were living at the property, and the dead adults were the children's parents.

A spokesperson for Lancashire Fire and Rescue said: "At 2.35am on Wednesday, July 17, four fire engines from Blackpool, South Shore, and Bispham fire stations attended a fire involving a domestic property on Peter Street in Blackpool.

“Crews used three hose reels, six breathing apparatus, and two positive pressure ventilation fans to fight the fire.

“Fire crews remain on the scene.”

Police say work is ongoing to establish the cause of the fire.

No arrests have been made at this stage.

A small number of other properties have been evacuated and several people are being supported by Blackpool Council.

Chief Superintendent Mike Gladwin, west divisional commander, said: “This incident has resulted in two people losing their lives and my thoughts are with their loved ones at this extremely distressing time.

“I know this tragic news will be met with great sadness in the local community and people will want instant answers.

“However, there are grieving loved ones still trying to come to terms with this devastating news. With that in mind, I would ask for patience and that people avoid unhelpful and upsetting speculation.”

Anyone who saw or captured anything suspicious on their CCTV, doorbell, or dashcam in the Peter Street area early this morning should call 101 or report it via the Lancashire Police website, quoting log 97 of July 17.
