The US believes it has enough evidence to prosecute a Swiss bank for its alleged role in a US$2 billion corruption scandal in Mozambique, according toReuters.

Russian state lender VTB has sued a Mozambican government company over an unpaid loan that is part of a US$ 2 billion multinational fraud scandal known as “tuna bonds,” which plunged the Mozambique into deep financial crisis,Reuters reported Monday.

An ex-Credit Suisse banker admitted last week he took kickbacks in a scheme that saw state-owned companies in Mozambique take US$2 billion in loans which helped drive the country into default on its debt,Reuters reported on Friday.

Financial giants Deutsche Bank and Credit Suisse stated on Friday they were willing to pay more than US$ 12 billion to settle United States investigations into the sale of toxic mortgage-backed securities of the type that helped cause the 2008 global financial crisis.

Swiss prosecutors have charged an ex-Credit Suisse wealth manager with fraud, misappropriation and criminal mismanagement, Bloomberg reported. The bank also faces a money laundering probe in Italy, Reuters said.
