Michael Porter appealed for information about his mother on Facebook
The family of a Dumfries woman missing on the Greek island of Crete are understood to have flown there after the discovery of a body.
Jean Hanlon, 53, who moved to Kato Gouves a number of years ago, was last heard from on Monday night.
The disappearance of Mrs Hanlon, previously known as Jean Porter, was reported to police and British Embassy officials in Greece.
The Foreign Office said Mrs Hanlon was reported missing on Thursday.
Her son Michael Porter has posted an appeal for information about his mother's whereabouts on the social networking site Facebook.
He said her family in the UK and friends in Crete were very concerned, adding that the last contact with her had been a phone call on Monday night from a bar in Heraklion.
The posting said: "It would be appreciated if anyone could provide any information as to Jean's whereabouts, as obviously her family in the UK and her friends in Crete are now very concerned for her safety.
"The last anyone heard from her was on Monday night when she telephoned a friend saying she was with a man at the Marina Cafe Bar near the port in Heraklion.
"If by some chance anyone has seen Jean, or have heard from her, or know of any information could they please contact myself Michael Porter, her son, or the British Consulate on Crete, the British Embassy in Athens, or the police".
A subsequent message on the Facebook site said Michael and his brothers were now on their way to Crete after the discovery of a body.
Dumfries and Galloway Constabulary refused to confirm the identity of the missing woman or if a body had been found, but a spokesman confirmed they were assisting the Greek authorities with their inquiries.
A Foreign and Commonwealth Office (FCO) spokeswoman said: "A British national was reported missing on 12 March in Greece.
"We are providing consular assistance. The local police are investigating".
