A former Nigerian justice minister accused of complicity in a billion-dollar oil scandal involving Shell and Eni was on Thursday granted bail by a high court in the nation's capital.

The judge asked him to provide surety of 50m naira ($139 000) before he could leave custody. The court then adjourned the case to March 26. Adoke, who also served as attorney-general between 2010 and 2015, was arrested last month on arrival from the United Arab Emirates where he had been detained on a Nigerian warrant over one of the West African state's biggest-ever corruption scandals.READ | Nigeria remands ex-minister in custody over oil scandalHe was accused of money laundering and collecting a bribe worth 300 million naira to broker the $1.3-bn sale of lucrative offshore oil block OPL245 to Shell and Eni in 2011.
