Anthony and Linda O'Malley went missing in September

BBC Wales has been told of a new sighting of a north Wales couple who disappeared after travelling to Spain to buy a villa six months ago.

Details of the new sighting of Anthony and Linda O'Malley from Llangollen - apparently accompanied by a mystery man - will be revealed in the current affairs programme, Week in Week Out on Wednesday.

Researchers have been told that the man took the couple to view a villa in the hills behind the town of Villajoyosa, near Alicante, in September.

But despite police appeals for information, he has never come forward to help the inquiry.

The unidentified man showed the O'Malleys around the property and helped them to begin negotiating with the owner.

But while he claimed to be an estate agent, he did not leave his name and contact details, and never contacted the owner of the villa again.

The programme has now passed on the information to detectives from North Wales Police, who were preparing to pass on the details to their Spanish counterparts through Interpol.

The documentary shows Mr O'Malleys brother Bernard O'Malley's journey to Spain as he attempts to uncover any clues the police may have missed.

Following information given to the family by a psychic astrologer, he travelled to the area surrounding the villa and spoke to the owner for the first time.

The owner has described the missing couple as a happy and pleasant couple who got on well.

Bank cards

Bernard O'Malley believes the news has finally scotched speculation in the press that the couple had had a domestic dispute.

The documentary also uncovers new evidence about the spending spree which stripped the couple's bank cards of thousands of pounds in a matter of days.

In all, �20,000 of the couple's money was spent in stores and withdrawn from cashpoints round southern Spain.

Bernard O'Malley said none of the credit card receipts showed the couple staying in a hotel or eating at local restaurants during the week leading up to 13 September, when they were due to fly home to the UK.

And North Wales Police have confirmed they can now prove forensically that someone other than the O'Malleys used their credit card to make large purchases.

And it is the credit card fraud, detectives have said, which could hold the key to solving the case.

The programme also examines the progress of the police investigation.
