Biker (19) suffers life-threatening injuries in Manvers collision

Three motorbikes were travelling along Manvers Way towards Mexborough at around 6pm when one of the riders, thought to be using an off-road pit bike, clipped the central reservation and crashed into a lamppost, a police spokeswoman said.

The 19-year-old man was taken to hospital with life-threatening abdominal injuries, she added.

Officers believe that the two other motorcyclists returned to the scene shortly before emergency services arrived and removed the bike. 

Sgt Adam Renshaw said: “A number of witnesses stopped and called 999, but the other motorcyclists did not stop at the scene.

"We would really like to speak to these two people as part of our enquiries; they may have information that will help us understand what happened. I’d also urge anyone who knows anything about the location of the bike to get in touch. 

“We’re also keen to hear from anyone who has dashcam footage of the moments prior to the collision, or saw what happened last night."

Anyone with information should call 101, quoting incident number 738 of July 23.
