A man has been arrested in connection with the murder of a Witney couple in Wales in 1989.

Peter and Gwenda Dixon, who were in their early 50s, were murdered on the Pembrokeshire coastal path above St Bride’s Bay in July, 1989. The couple were shot at close range with a shotgun.

In 2007, police launched Operation Ottawa into the deaths of the couple, who lived at Moorland Road, Witney, and were on a camping holiday.

The specialist team are also looking into another unsolved case from 1985, of Richard and Helen Thomas, who were also murdered in 1985 at nearby Milford Haven.

Deputy Chief Constable Andy Edwards, of Dyfed-Powys Police, said: “Today a local man has been arrested on suspicion of the murders of Helen and Richard Thomas at Scoveston Manor in December, 1985, the murders of Peter and Gwenda Dixon on the Pembrokeshire coastal path in 1989, and a serious sexual assault and attempted robbery in Milford Haven in 1996.”
