A bike worth more than £5000 was stolen by thieves while the cyclist was in an ambulance with his injured brother.
The silver Whyte E-150 was pinched from the Buzzard’s Nest car park in Glentress Forest near Peebles, Scottish Borders, at around 7.40pm on Sunday.
While the victim attended to his sibling, a man was seen removing the bike from a rack on the back of a car before cycling off.
He was then followed by a dark silver transit van with red, white and blue lettering on the sides, possibly featuring an inverted triangle.
The bike, which had a 22in frame, a black gel seat, Yeti handgrips and blue dust caps, is valued at £5100.
The first suspect is believed to be in his mid-20s, around 5ft 10in, and was slim. He was wearing grey jogging bottoms and a bike helmet.
The second suspect was described as in his early-20s, of slim build, and was wearing cycling gear.
Enquiries into the incident are ongoing.
Constable Barry Taylor said: “The victim’s brother had injured himself on his bike prior to the incident and the victim was attending to his brother in an ambulance when the theft took place.
“We would encourage anyone who may have seen the van in the area before or after the incident or has seen a bike matching the description to get in touch.”
