A fire that killed two people at a flat is being treated as suspicious, police said.
Two people died and two are being treated in hospital for multiple injuries after police officers discovered the fire at a second floor flat in Church Road, Heston, west London, in the early hours of this morning.
An injured woman, believed to be 30, was found in the street close to the burning flat and was pronounced dead at the scene shortly after 2.30am.

A second person, believed to be a man, was found dead inside the flat during a search by firefighters.
An 18-year-old man and a 37-year-old man were taken to St Mary's Hospital and the 18-year-old has since been transferred to a west London hospital.
Police said both men remain in a serious condition but their injuries are not believed to be life threatening.
The woman and two men are believed to have jumped from the burning building before firefighters arrived shortly after 1.30am.
The Metropolitan Police Service said: "The fire is being treated as suspicious."
Eight fire engines and around 58 firefighters battled to control the blaze which has been extinguished, the London Fire Brigade said.
