A man was threatened with violence in a robbery on a Swindon roundabout.
Police are investigating the incident, which happened at Transfer Bridges on 30 March.
A man, aged in his 50s, was walking under the railway bridge when he was approached by two males – who demanded he hand over money.
The victim gave the suspects money from his pockets and they fled the scene on foot.
They are described as white males – and were wearing black hoodies and trainers.
The robbery took place between approximately 9pm and 9.15pm. Police want to trace drivers who may have captured dashcam footage in the area at that time.
A spokesperson for Wiltshire Police said: “Enquiries are currently ongoing and we would ask anybody who witnessed the incident, or anyone who may have been passing in a car with dash cam to get in touch.
“Call 101 and quote crime reference number 54240036686. Alternatively, call CrimeStoppers anonymously on 0800 555 111.”
