Police have released a picture of a woman suspected of fleecing a man of more than £180,000 on a dating website.
The woman, who police believe could be part of an international crime syndicate, used the names Christy Dunn, Martha Cameron and Miranda Stinson.
A 43-year-old man from Manchester was conned out of more than £180,000 by the woman he first met on Match.com in February 2014.
They communicated through various messenger apps and video calls when the woman asked the man for money several times.
The woman, who spoke with an American accent, promised the victim a relationship and then used emotional blackmail and the promise that she would return the money.
He paid several amounts of cash into accounts with links to Bristol.
Detective Constable Simon Da Costa of Avon & Somerset police said: “We want to speak to this woman about the fraud.
“She speaks with an American accent and has links to the Bahamas, South Africa, Botswana, London and Bristol.
“We believe this scam is likely to be part of a wider criminal operation targeting lonely and vulnerable people online.”
Police fear there may be more victims of the scam and Mr Da Costa added: “We really need to find this woman so if you have any information about where she may be, or if you have been a victim, please call us.
Anyone with information should call 101 and quote the reference number 12939114.
