When last seen he was heading in the direction on Princes Street.

Detective Sergeant Keith Taylor, of Edinburgh CID, said: “Thankfully nobody has been injured as a result of this incident but the member of staff has been left evidently shaken.
“Although this happened in the early hours of the morning, I would ask that if anyone noticed a man matching this description or anyone acting suspicious in the area to get in contact with police.
“I would also ask if anyone has any dashcam or CCTV footage of the surrounding area and may have information that could assist with our investigation to come forward.”
