Police in South Africa say they have arrested a man on suspicion of murdering his wife and two daughters near Bedford.

Nothabo Zandile Tshuma, 42, and Natalie, 15, and Nala, five, were found dead at the family home on Monday.

Lead suspect Tshuma Zandile Tshuma, 42, a Zimbabwean national, left the country via Heathrow Airport on a British passport two days earlier.

On Friday, South African police spokesperson Athlenda Mathe said officers in the country had “successfully located and arrested” Tshuma in Johannesburg.

“Let this be a stern warning to criminals across the world, that South Africa is not a hide-out for fugitives,” said Mathe, speaking to reporters.

“If you commit serious crimes anywhere in the world and think you can evade justice by fleeing to South Africa, you are mistaken.

“We will trace you, we will find you and we will arrest you.”

The suspect was due to appear in court on Monday, Mathe said, adding that the “necessary legal and extradition process” would take place alongside UK authorities.

Det Insp Lee Martin, of Bedfordshire Police, said: “This has been a fast-moving investigation which has involved multiple law enforcement partners, including the National Crime Agency, Interpol and authorities in both Zimbabwe and South Africa.

“Thanks to the tireless work and dedication of all those involved, we have managed to swiftly locate and arrest Ndodana Mkhanyisi Tshuma.”
