A man in his 40s died this morning when a fire broke out in an upstairs bedroom of a home in north Lynn. He has been named locally as Chris Flegg.
Police were called to the house in Alice Fisher Crescent at around 6.20am to help the fire service.
Fire station manager Simon Mason, who is at the scene, confirmed an elderly woman was rescued from the house and a man in his 40s died.
The man has been named locally as Chris Flegg, who lived with his mother Carol.
'It's still incredibly early days,' Mr Mason said. 'What we've got is a significant fire in an upstairs bedroom. We helped one occupant out from a ground floor bedroom.
'What we believe happened was a member of public came past on his way to work. He saw the fire and raised the alarm.
'He has done a fabulous job in assisting. The early detection of fire is very important to us.'
The elderly woman was taken to hospital with smoke inhalation.
A seal is in place around the house and officers will be working with fire investigators to establish the cause of the fire.
A neighbour, who preferred not to be named, said she saw big flames billowing out of one of the upstairs windows an immediately called emergency services.
'We are quite united in this street and we all look out for one another. It's a nice neighbourhood and we all seem to know one another,' she said.
The neighbour added she spotted a man standing on top of his van in an effort to see into the window.
The man then knocked on one of the next door neighbour's houses and, together, they got into the house through a side door.
She said the fire brigade then arrived at the scene.
Another neighbour said: 'This is a nice, quiet neighbourhood and they were nice people. It was a horrendous shock. When I got up I looked out of the window and I thought my eyes had gone funny because of all the ambulance lights and the fire engine.'
An accelerant detection dog helped the investigation team in finding what had caused the fire.
Mr Mason said: 'We use them to rule in or rule out the possible causes. With a fatal investigation we try to rule out every possibility to lead us to the credible cause of fire.'
