Friends have paid tribute to the mother-of-one, named locally as 22-year-old Namara Whisker, who died in the early hours of Saturday when the car she was travelling in plunged into the River Avon.
The former business studies student, from the Easton area of Bristol, was described as "the kindest person you could ever meet".
School friend Shawnika Sergeant, 22, said: "She was so pretty, bubbly and a special girl. I could not believe it when people started texting me. I have known her for so long, it is hard to take."
Avon and Somerset Police Inspector Paul Winship dismissed the suggestion that a police vehicle may have been in pursuit of the BMW as it crashed through iron railings in Bristol city centre into the river.
"I can confirm this was a straightforward accident involving a single car going off the road," he said. "It was not a pursuit, and so the Independent Police Complaints Commission has not been informed."
Police officers who dived in to rescue passengers from a car which plunged into a river yesterday, killing a mother-of-one, are back at work today.
Six members of Avon and Somerset Police were taken to hospital in Bristol after leaping into the chilly water at around 4:00am yesterday.
Police Inspector Paul Winship said: "The six officers were treated by medics for the effects of being in the water. As far as I am aware, they are back on duty today."
The area manager for Avon Fire and Rescue Service said the attempt to rescue the occupants of a car that drove into the River Avon was a complex operation involving multiple agencies:
– Denis McCann, area manager at Avon Fire and Rescue Service
We responded from there with a rescue pump which has enhanced rescue equipment on it and then we had a specialist water rescue team from Bedminster, which is one of the neighbouring city centre stations.
They have access to a rescue boat, inflatable rafts, inflatable walkways and dry suits. They are specially trained to make entry into moving and still waters.
There was one person trapped in the vehicle who was removed by Fire and Rescue Service personnel using the rescue boat across to a nearby jetty ...
An Avon and Somerset Police spokesman said: "Two people have been arrested on suspicion of causing death by dangerous driving."
Police have appealed for witnesses who may have seen a car leave the road and enter the Avon River at St Philip's Bridge at Temple Back in Bristol. The incident happened around 4am this morning.
Inspector Paul Winship of Avon and Somerset Police said:
– Inspector Paul Winship, Avon and Somerset Police
We are obviously appealing for witnesses. It's a very busy part of Bristol even at 4 o'clock on a Saturday morning.
Fire and ambulance were also at the scene. We are not looking for anyone else in connection with the incident.
The scene is still closed while we are continuing with our inquiries.
At least six police officers are being treated in hospital after diving into a river in a bid to rescue the five occupants of a car which had crashed into the water.
One woman inside the vehicle died but the other occupants survived the incident in the River Avon in Bristol early today.
Police said at least six officers dived into the river in a bid to save the car's occupants and were later treated in hospital as a precaution.
A man and woman were rescued and are currently helping police with their inquiries.
Two other women who were also rescued are being interviewed as witnesses.
