At just after 1.30pm on Friday 18 September, a woman was approached by a man as she waited on the platform at Camborne railway station who told her that she owed him money.
The woman got up and ran away from the man, dropping her handbag as she did so. The man then chased her and grabbed her by the neck before a member of rail staff intervened.
The man then returned to where the woman ran from and took her handbag before leaving the station.
Thankfully, the victim did not suffer any serious injuries.
Officers believe the man in the CCTV image may have information which could help the investigation.
