Angolan vice-president Manuel Vicente is facing corruption charges in Portugal as part of an investigation in Lisbon.
Vicente also faces charges of money-laundering and forgery.
The vice president is suspected of bribing a Portuguese magistrate to favour him in two investigations, the BBC reports a statement to say.
Investigators allege Mr Vicente paid Portuguese magistrate Orlando Figueira, who was arrested a year ago, about 760,000 euros ($808,000; £647,000) to drop two investigations that involved alleged money laundering and Angolan investments in Portugal while he was the head of the state oil company Sonagol.
The magistrate, Mr Vicente’s lawyer, and his representative in Portugal are also accused in the case, called Operation Fizz.
Vicente is however reported to have denied the allegations.
