Former Credit Suisse Group AG banker Detelina Subeva pleaded guilty on a U.S. charge that she conspired to launder money from a scheme involving $2 billion in loans to Mozambican state-owned firms, Reuters reported.

Subeva said that in 2013, her boss, Andrew Pearse, who was then head of the Swiss lender's global financing group, told her that he received a $1 million kickback linked to a $372 million loan to a Mozambican state-owned firm, with the kickback coming from Abu Dhabi-based naval contractor Privinvest, Reuters said.

She claimed Pearse transferred roughly $200,000 of the kickback to her account, and said she accepted the funds despite knowing that they were "proceeds of illegal activity."

Subeva has been released on bail, the news agency wrote, noting that it is unclear whether she agreed to cooperate with U.S. prosecutors.

Pearse is also charged in the case, along with fellow former Credit Suisse banker Surjan Singh and former Mozambique Finance Minister Manuel Chang.

In April, Swiss anticorruption group Public Eye filed a criminal complaint against Credit Suisse related to fraud in the bank's handling of the loans to Mozambique, months after the bank was sued by the African nation over so-called commercial contracts.
