At least 17 people have been injured, some seriously, after two cars crashed at a modified car meet in Stevenage.
The incident took place in Stevenage, Hertfordshire, on Thursday evening as hundreds of people gathered to admire cars at the event which was raising money for charity.
Footage posted on social media showed one car emerging onto the main road while another vehicle was passing at speed.
They collided, causing both cars to hit bystanders on the side of the road and on the central reservation.
A spokesman for Hertfordshire Constabulary said: “I am not aware of any fatalities or arrests at this stage, however investigations are ongoing.
“We are working with the road policing unit and local policing teams for further updates and will be in touch in due course.”
A witness wrote on Facebook: “Horrific incident in Stevenage.
“A car has ploughed into at least 10/15 people on the side of a road who were watching on.
“Must be 30+ emergency services on the scene.
“Thoughts are with all involved, looks so bad.”
“Kids on the floor not moving”
Ciaran O’Connor, who witnessed the crash, said: “You could just see kids on the floor not moving.
“I saw at least ten people injured.
“One boy had quite a bad arm injury,” he told Mirror Online.
Police have urged any witnesses to get in touch and have asked anyone with footage of the incident to retain it.
The accident happened during a weekly meet of the modified car club Cruise Herts.
A post on the group’s Facebook page read: “This Thursday night meet is an extra special meet we as a group are raising money for the excellent charity of 4Louis who help supporting families through the heartache of miscarriage stillbirth and child loss.
“This is a Strictly Static Meet & Any Antisocial Behaviour Will Not be Tolerated.
“Any Such Behaviour will be Dealt with by the Local Authorities.
“So strictly NO Wheel Spins NO Burnouts and NO Drifting.”
Cruise Herts club has since said it will not be hosting any further events.
