A 23-year-old man has died after being hit by a vehicle at a car meet in Lincolnshire.
Police arrested a 17-year-old boy on suspicion of causing serious injury by dangerous driving. He has been released under investigation.
Connor Richards, of Sheffield, was taken to hospital following the collision in Flixborough industrial estate, near Scunthorpe, but died of his injuries on Thursday.
Police said one other victim was still in hospital and was in a stable condition.
Others who were taken to hospital had now been discharged.
Eleven bystanders were injured when a Ford Fiesta ploughed into a crowd, including children as well as a pregnant woman. Emergency services were called to the scene.
A video clip showed a person sitting on the rear spoiler of a BMW wheel-spinning in a car park, where the meet originally gathered. Skidmarks were left.
A witness described some drivers “getting carried away and showing off”.
A separate clip from later in the day appeared to show a person being carried on the bonnet of a red car that was braking heavily.
One of the wounded, Georgia Wood, 22, lost her unborn baby and suffered a bleed on the brain.
Humberside Police said officers were still investigating. The force said: “We have gathered a huge amount of footage and information following the collision.
“However, if anyone has footage that they have not provided to the police, we urge them to get in touch on our non-emergency number 101 quoting log 531 of 24 September.”
The day after Mr Richards’s death, Inspector John Rickells said: “This was a multi-agency incident response and we worked with our emergency service colleagues to provide emergency first aid and establish the circumstances of the incident.
“As part of our investigations, a 17-year-old has been arrested on suspicion of causing serious injury by dangerous driving. At this time our investigations are at a really early stage, and we will release more information when we are able to do so.
“We are aware that a number of people left the scene prior to emergency services arriving, and they may have witnessed what happened.
“We would ask that anyone who may have mobile phone or dashcam footage of the vehicles involved both prior to and at the time of the collision to contact us so that we can establish exactly how the incident happened.”
