Police are continuing their appeal for information one week after a female healthcare worker was coughed on by a teenage boy.
The woman was driving along the unclassified road from Inchmarlo Golf Course to Brathens Wood near Banchory, around 1.40pm on Friday last week, when the incident happened.
Stopping her car after being flagged down by a youth, she was then coughed on directly in her face and told she would now get coronavirus.
The young offender, who is believed to be aged between 13 and 16, ran off in the direction of the woods laughing before joining a larger group of teens.
He has been described as being around 5ft 6ins, slim build with a local accent and wearing a light grey hoodie, a black jacket and black or dark blue joggers.
Officers are keen to speak with a young BMX rider who was spotted in the area an hour after the assault wearing a black full face helmet.
He was in a group of four; two with bikes and two on foot.
Sergeant Garry Garrow, of Banchory Police Station said: “This was more than just a prank, it left the woman distressed and fearful. Anyone who knows who any of these youths are should get in touch immediately.
“In particular we are asking for help to trace the young person seen on the black BMX type bike. I would ask parents if they think this may have been someone from their family to get in touch. Likewise, the person concerned should call us.
“I would like to thank those who have already contacted us with information. Banchory is a great community and when something like this occurs, everyone feels it. This behaviour was despicable and in the current climate, absolutely unacceptable.”
Anyone with dash-cam footage or CCTV images from the Brathens Woods area including the road between Banchory and Torphins, known locally as the Glassel Road is encouraged to contact police by calling 101.
