A vulnerable woman who disappeared last month had a "side of her life" which she kept private, police have revealed.

Margaret Fleming, 36, was last seen by her two carers at her home in Inverkip, Inverclyde, at around 5.40pm on Friday, October 28.

Officers have been carrying out extensive enquiries since her disappearance but have so far drawn a blank and she remains missing.

Police on Wednesday issued a further appeal for help in the search for Ms Fleming, who is believed to have learning difficulties, and described it as an "unusual missing persons case".

They also outlined that Ms Fleming was a student at James Watt College in Greenock from 1996 to 1997.

Officers are keen to speak to anyone who remembers her from then and who might have been in touch with her over the years.

Ms Fleming is described as around 5ft 5in with collar-length black hair and brown eyes.

She has a heavy build, although her weight sometimes fluctuates, and she was wearing a green tartan fleece or jumper, dark jeans or trousers, and dark Karrimor boots when she was last seen.

Chief inspector Elliot Brown, area commander for Greenock, said on Wednesday: "Police Scotland is continuing significant enquiries into the disappearance of Margaret, and we've been thankful for the response from the public so far.

"I would like to make it clear that finding out what has happened to Margaret is a priority for my team here in Greenock.

"We are currently working with limited information and whilst it does seem like this is quite an unusual missing person case, it is challenging, however, we've a number of lines of inquiry we are working on and I would like to stress that this is still a missing person inquiry."

He added: "As we continue to try to piece together Margaret's life, we understand she kept a side of her life quite private so we're trying to look into this in a bit more detail to see if this will help with our enquiries.

"We are working backwards to try to find out more about Margaret, so we've been speaking to friends and family members to establish a clearer picture of her life over the years.

"Again, we do know that Margaret was a student at James Watt College, Greenock, from 1996/97 therefore we'd be keen to speak to anyone who remembers her from then, and who might have been in touch with her over the years.

"I would ask anyone with any information, no matter how irrelevant it might seem, to contact police at Greenock via 101."
