Police have released an image of a man they want to track down following a serious incident in Edinburgh more than six years ago.
Investigating officers said there is “no reason to believe” the man was involved in the incident itself, but he may have witnessed something that could assist with the inquiry.
The incident occurred within Newmills Road in the Balerno area during the early hours of August 27, 2015.
The man captured on CCTV was on the number 44 bus travelling west from Edinburgh city centre towards the Balerno area late in the evening of August 26.
He was seen to get off the bus in Newmills Road shortly before midnight and detectives believe he may have “vital information” relating to the incident.
Detective inspector Jon Pleasance, of Edinburgh CID, said: “This man may have witnessed something that could assist with our investigation and therefore it is vital we speak to him.
“There is no reason to believe he was involved in the incident itself, and he may have not realised that what he potentially saw or heard could assist police.
“I would ask if you are this man, or you recognise this man, please get in contact with police.
“Although this incident took place in 2015, we are determined to bring the offender to justice and are appealing for any information that can help with our enquiries.”
