Prosecutors in South Africa have announced plans to file more charges against Henry Okah, the alleged mastermind of a deadly bombing in Nigeria last year.
News reports on Tuesday quote prosecutor Shaun Abrahams as saying the additional charges relate to a March 2010 bombing in the southern Nigerian city of Warri. Abrahams says Okah will be charged with terrorism and conspiracy for the blast.
Authorities arrested Okah in South Africa on October 2, a day after bombings in the Nigerian capital, Abuja, killed 12 people. The explosions occurred as Nigerians marked their Independence Day.
Investigators say Okah was a leader of the Movement for the Emancipation of the Niger Delta (MEND), the group that claimed responsibility for the October blasts.
Okah has denied having a role in the attack. Earlier, he pleaded not guilty to terrorism charges in connection to the incident.
