A couple trapped in their submerged car for two hours have been rescued in what eyewitnesses have dubbed "a Christmas miracle".
Matt and Alex Emmerson presumed the car was empty when they spotted it from their bathroom window, but after 15 minutes the emergency crews arrived and a daring rescue began.
Mr Edmonson, 44, told the BBC: "Whoever this poor couple were, they were in there for a long time - close to two hours.
"The water must have been freezing."
Mrs Emmerson, 42, added: "I just assumed that there would be nobody in there.
"Because normally people leap out and wade to safety before it gets to that point.
"We just thought it was another car that had been abandoned."
Her husband - who called the rescue a "Christmas miracle" - said a firefighter went straight into the water and smashed a car window to gain access "despite the water coming up to his chin".
Mrs Emmerson, while recording the rescue, said: "He's literally up to his armpits."
The firefighter can be heard shouting to colleagues: "Guys I'm unsure, I don't know if there's anyone in here."
Moments later he spots a woman and smashes the window before pulling her out.
She appeared to be in a state of shock.
Mr Emmerson said: "I couldn't see anyone come out of that alive.
"He was shouting to her to find out if there was anyone else in there and she was in a real state of shock."
A man was then found inside and pulled out.
The couple were taken to hospital for assessment according to the East of England Ambulance Service, but no further details were given.
Norfolk Fire and Rescue Service said it had received more than 300 calls about flooding since Wednesday afternoon.
The Emmersons said the area of Thorpe End in Norfolk where they live often floods in heavy rain.
