Police are mounting high visibility patrols in the area.
Det Insp Ray Birnie said: "Enquiries are ongoing into the incident and I would like to appeal to the public to come forward if they have information that which may assist us.
"We are particularly keen to trace and speak to a man who has been described as white, aged 30-40, around 5ft 11in, thin build with light brown hair and stubble and who spoke with a Scottish accent.
"He would have been wearing a dark blue jacket, dark "hoodie" and light coloured jogging bottoms."
