Three former Credit Suisse Group AG bankers were arrested in London on Thursday on U.S. charges that they took part in a fraud scheme involving $2 billion in loans to state-owned companies in Mozambique, a spokesman for U.S. prosecutors said.

Axar.az reports citing Reuters that Andrew Pearse, 49; Surjan Singh, 44; and Detelina Subeva, 37 were charged with conspiring to violate U.S. anti-bribery law and to commit money laundering and securities fraud. They have been released on bail in London while the United States seeks extradition.

“The indictment alleges that the former employees worked to defeat the bank’s internal controls, acted out of a motive of personal profit, and sought to hide these activities from the bank,” Credit Suisse said in a statement. It added that the bank will continue to cooperate with authorities.

Reuters notes that the arrests came five days after former Mozambique Finance Minister Manuel Chang was arrested in South Africa as part of the same criminal case.
