Mozambique has launched legal action against a French-Lebanese billionaire, Iskandar Safa, whose shipbuilding company is at the heart of a $2 billion debt scandal, officials said Friday.
A source at the attorney general's office, in an emailed reply to AFP, confirmed "a case is ongoing" without giving details.
In London, an official at the High Court commercial division told AFP the Mozambican government had filed proceedings there against Safa.
The papers were submitted on July 31 and no date has been set yet for the hearing, the source said.
Safa is CEO of a giant shipbuilding company, Privinvest, which signed contracts with Mozambique state companies to supply ships and national maritime security.
The government's legal moves came after testimony in a New York court last month by a former Credit Suisse banker, Andrew Pearse.
Safa, he said, had wired him "millions of dollars in unlawful kickbacks from loan proceeds and illegal payments" for help in securing loans from the bank.
The scandal is rooted in loans of $2 billion (1.8 billion euros), undertaken by the government between 2013 and 2015, to buy a tuna-fishing fleet and surveillance ships.
The government admitted it borrowed the money secretly, forcing international donors to suspend aid.
An independent audit found that a quarter of the loans had been unaccounted for, and another $750 million, used to buy equipment, had been over-invoiced.
The United States alleges at least $200 million was spent on bribes and kickbacks.
Several people have been arrested both in Mozambique and abroad.
They include Mozambique's ex-finance minister, Manuel Chang, who is said to have received $12 million for allegedly signing off on debt guarantees.
Chang was arrested in South Africa last year on a US extradition request.
In an ongoing tussle over where he could stand trial, the Mozambican government this week said it would fight attempts to extradite him to the US after the South African government halted plans to send the minister to his home country.
When the hidden debt was revealed, Mozambique -- which relies on donor aid and is one of the world's poorest countries -- was plunged into the worst financial crisis in its history.
The US Department of Justice has accused three former Credit Suisse workers of helping to create $2 billion in maritime projects as a front for the scam.
They were arrested in London in early January. In May one of them pleaded guilty to conspiracy to launder funds over the case.
Safa's lawyers and spokesman were not immediately available for comment.
