A nephew of Equatorial Guinea's President Teodoro Obiang Nguema, who was at the centre of a sex tape scandal last year, has been sentenced to eight years in prison for embezzlement.

Baltasar Ebang Engonga, the former head of the National Financial Investigation Agency, diverted money for personal use, a court ruled.

Nicknamed "Bello" because of his good looks, the married Engonga gained notoriety last year, when he appeared in leaked videos having sex with different women - many of them wives and relatives of people close to the centre of power.

The leak occurred while he was in detention, accused of depositing a huge sum of embezzled money into secret accounts in the Cayman Islands.
