A man was this morning still being quizzed by detectives over the murder of an Oxfordshire couple 20 years ago.

The 64-year-old man was arrested in Letterstone, Wales, yesterday, on suspicion of the murder of Peter and Gwenda Dixon, of Moorlands Road, Witney, in July 1989.

Mr and Mrs Dixon’s bodies were discovered on a coastal path at a Welsh beauty spot. They had been shot dead.

Mr Dixon, 51, had his hands tied behind his back and his wallet was missing, while Mrs Dixon, 52, had had her clothes partially stripped off her.

The arrested man is also being held over the killing of another holiday couple in Wales 24 years ago and a robbery and sex attack.

Following the arrest, Dyfed Powys Police have 24 hours to question the man, but could apply for a further 12 hour extension today.
