Madagascar President Andry Rajoelina (R) reviews French troops upon his arrival at the Elysee Palace in Paris, France, 29 August 2022. EPA-EFE/YOAN VALAT Romy Andrianarisoa, who works for Madagascan President Andry Rajoelina, was arrested along with a French associate at a meeting in London where the NCA said they were believed to have attempted to solicit a bribe to secure licences to operate in the African island nation.
Neither spokespeople for Rajoelina's office nor representatives for the suspects were immediately available.
The NCA said the pair were seeking around 225,000 pounds ($286,000) in upfront charges as well as a 5% equity stake.
"I am grateful to Gemfields for bringing this matter to our attention and for their ongoing cooperation with the investigation," Andy Kelly, head of the NCA's international corruption unit, said in a statement.
"Their quick reactions to engage the NCA have been critical to our ability to pursue this case."
The UK-based miner owns the Faberge jewellery brand, operates ruby and emerald mines in southern Africa and has been exploring setting up operations in countries including Ethiopia and Madagascar.
Andrianarisoa, 46, and French national Philippe Tabuteau, 54, appeared in court on Saturday and have been remanded in custody until their next hearing in London on Sept. 8.
Gemfields declined to comment.
