An 86-year-old man has been arrested in connection with the murder of a couple on their farm in Wales more than 30 years ago.

Harry and Megan Tooze were found dead in a cowshed with gunshot wounds at their farm in Llanharry, near Cardiff, Wales, on 26 July 1993.

South Wales Police began a forensic review of the case in 2023 in the hopes of uncovering new evidence in the murders of Mr Tooze, 64, and Mrs Tooze, 67.

The force arrested a man on Wednesday and he is currently in police custody.

Detective superintendent Mark Lewis said: "While this arrest is clearly a significant development in the investigation, our inquiries are very much ongoing.

"This case has affected many people over the years, and our aim is to find the answers to the unanswered questions which remain about their deaths over 30 years on.

"Even with this passage of time, I appeal to anyone who has any information about the murders to come forward and speak to police."

The couple's last known whereabouts was when they left their house to collect their pensions in Llanharry on the morning of 26 July 1993.

Neighbours reported hearing two gun shots at around 1.30pm.

However, emergency services were not alerted due to the noise being considered normal on a rural farm.

Police were called and attended the Ty Ar y Waun farm and discovered the bodies of the couple in a cow shed after a regular phone call from their daughter went unanswered.
