Two people have died after a car plunged into a canal in Bristol.
Dozens of emergency crews were called to the scene on Sunday evening.
Eyewitnesses described the car as "sinking like a stone" after it crashed through a barrier and into the city's Feeder Canal.
Recording and rehearsal studio boss Steve Mallison, 44, was helping bands unload gear into the nearby RS Studios when the incident unfolded.
He said: "The car came down the road near Short Street and failed to stop when it got to the turning by Feeder Road.
"It went straight into the railings and literally went straight to the bottom.
"A middle aged couple in the street nearby were really traumatised by what they had seen.
"Loads of emergency services then raced down to the scene - I've never seen so many police cars and ambulances in quick succession.
"There's been a few cars which have gone in the river in the past 10 or 15 years we've been here, but none as bad as this.
"I knew straight away that it was very serious - especially after seeing 40 emergency vehicles and two river dive teams."
Avon and Somerset Constabulary said it was called to the incident at around 6pm.
A force spokesman said: "The bodies of two people have been located following the road traffic incident off Feeder Road.
"The incident took place when a car, driving from the direction of Short Street, failed to stop on Feeder Road and drove into the canal.
"At this time, the vehicle has yet to be recovered, but we do not believe anyone else was inside the car at the time of the incident."
Police added several road closures are likely to remain in place "for some time" and are advising motorists to avoid the area.
Anyone who may have witnessed the incident or seen the vehicle beforehand, is asked to contact 101 and quote log number 741.
Avon and Somerset Police also said the bodies of the two deceased had yet to be formally identified.
A message on its official Twitter page read: "Both bodies located at incident off Feeder Rd are adults. Please do not speculate online. Our thoughts are with both families."
