Police say they are making enquiries after broadcaster Dan Walker was hit by a car while on his bike.
Following the incident, the 45-year-old tweeted a series of images of his bloodied and bruised face while sitting in an ambulance.
“No arrests have been made and enquiries are ongoing,” a spokesperson for South Yorkshire Police told Sky News.
It comes as dashcam footage of the incident was shared by The Sun, showing the moment of the collision.
The video shows Walker, cycling on his bike before appearing to be hit by the front left-hand side of the vehicle and then falling to the floor.
The driver whose dashcam recorded the incident told the newspaper: “I looked in my mirror and saw him roll across the road after he’d been hit.
“It was quite shocking – certainly something you don’t see every day. He’s lucky to be alive.”
Walker took to Twitter to share details about the incident on Monday.
Sharing a picture of himself with two paramedics from Yorkshire Ambulance Service, he wrote: “Bit of an accident this morning (Monday).
“Glad to be alive after getting hit by a car on my bike. Face is a mess but I don’t think anything is broken.
“Thanks to Shaun and Jamie for sorting me out and the lovely copper at the scene.”
Hours later, Walker gave his followers an update saying the helmet he was wearing saved his life.
Walker, who left the BBC to join Channel 5 last year and took part in the 2021 series of Strictly Come Dancing, warned other bike users to “get one on your head”.
A spokesperson for Yorkshire Ambulance Service NHS Trust told Sky News: “Our staff do an amazing job every day helping thousands of patients.
“We are very proud of the care they provide and would like to send our best wishes to Dan Walker for a speedy recovery.”
