The girl and her friend, also 14, were seen in the company of two men walking along the foreshore at Alexandra Parade, Dunoon, at 23:00 on 28 June.

As the girls walked back alone to a bus stop, a member of the public called police after becoming concerned about the way they were behaving.

The girl later told officers that she had been raped by one of the men.

Det Insp Douglas Wilson, of Strathclyde Police, said: “This enquiry is at a very early stage and we have still to clarify exactly what happened, however, one of the girls has told police that she was seriously sexually assaulted by one of the men.

“The suspect is described as of Asian appearance, between 19 and 40 years of age, 5ft 5in in height, average build, short dark hair, dark eyes and was wearing a long sleeved purple top.

“He was with a second man, also believed to be of Asian appearance, around 5ft 3in in height, of a heavier build, between 19 and 40 years of age, dark hair and eyes and was wearing a yellow long sleeved top.”

CCTV images

Det Insp Wilson said officers had been checking CCTV and carrying out door-to-door enquiries the area in an effort to trace the men.

He added: “Alexandra Parade is normally quite busy with pedestrians and passing traffic and I would appeal to anyone who was in the area between 2230 and 2300 hours on Thursday night to come forward.

“On checking CCTV, we saw at least three dog walkers and two young men in the area at that time.

“I am in no way connecting them to the incident other than that they might have seen or heard something that will help us with our enquiries.”
