(Bloomberg) -- Former OPEC president Diezani Alison-Madueke was charged with bribery offenses in the UK, after an investigation by the country’s National Crime Agency.

Alison-Madueke, 63, is accused of accepting bribes during her time as Nigeria’s Minister for Petroleum Resources in exchange for oil and gas contracts, the agency said in a statement Tuesday. The former minister is alleged to have benefited from at least £100,000 ($127,300) in cash as well as flights on private jets and luxury holidays.

A lawyer for Alison-Madueke in Nigeria couldn’t immediately comment.

“We suspect Diezani Alison-Madueke abused her power in Nigeria and accepted financial rewards for awarding multi-million pound contracts,” Andy Kelly, the head of the NCAs’ international corruption unit, said.

Alison-Madueke, who lives in north London, is alleged to have accepted furniture, renovation work and staff at the properties, as well as the payment of private school fees.
