Police have released an image of a man they want to track down following an incident on board a bus earlier this year.
The incident occurred within Aberdeen’s Albyn Place at around 6.50pm on Saturday, April 24.
Investigating officers believe the man captured on CCTV will be able to assist with their enquiries.
The man is believed to be aged between 40 and 50, around 5ft 10in, and was slim with brown/grey spikey short hair that was shaved at the sides.
He was wearing a blue medical mask, grey or blue joggers and a brown leather jacket.
He was also carrying a black rucksack that had lots of buckles and zips and some white patterns and stripes.
Police constable Hibbard said: “Our enquiries have been ongoing since this incident occurred and as part of our investigation we are releasing CCTV images of a man we believe could assist us.
“I’d ask the person himself, or anyone who recognises him and who can help us identify him, to contact officers.”
