CCTV images have been released after a man verbally abused and then threatened a victim outside a Stevenage One Stop shop.
The public order offence occurred on Broadwater Crescent at around 9.45am on Sunday, May 5.
The victim, a man in his 30s, was verbally abused and then threatened with what is believed to be a penknife by another man after leaving the One Stop shop.
The victim walked away and said he would call the police, after which the offender ran in the opposite direction.
Officers would now like to speak with the person pictured as he may have information which could assist the investigation.
