The mother of Nigeria’s Finance Minister Ngozi Okonjo-Iweala has been released five days after she was kidnapped, Delta state governor Emmanuel Uduaghan has told the BBC.
Kamene Okonjo, an 82-year-old professor, was seized from her home in southern Nigeria on Sunday.
Nigeria’s army said on Thursday that soldiers had arrested 63 people in raids conducted during the search for Okonjo.
Earlier this week, a finance ministry spokesman said that Mrs Okonjo-Iweala had been threatened recently.
It is not clear if Mrs Okonjo was held for political or financial gain.
Political motives had been suggested for the abduction. Ngozi Okonjo-Iweala’s drive to reform a corrupt economy ruffled powerful vested interests, especially fuel importers, and her mother was involved in local politics.
