Police are hunting two men after a cyclist was attacked in an attempted robbery on the Trans Pennine Trail in Doncaster.
A 40-year-old man was pushing his bike over the viaduct bridge from Cadeby towards Doncaster when he was approached by two strangers.
One of the men asked him the time and started talking about his bike before repeatedly punching the cyclist in his face.
Police said the cyclist managed to defend himself and run off from the men, dragging his bike with him.
One man was white, around 6ft tall and slim.
He was in his early 20s, had short, dark hair and was wearing a dark, short-sleeved T-shirt with jeans.
The other was also white, around 5ft 8ins tall and also in his early 20s.
He was wearing a dark burgundy long-sleeved hooded top with a large pocket at the front and dark jeans.
Witnesses or anyone with information about the incident at 1.55pm on Friday, May 8 should call South Yorkshire Police on 101.
