Former Zambian leader Rupiah Banda has been arrested and charged with abuse of power over a controversial oil deal.
He was arrested Monday and quickly released on bail. The former leader is scheduled to appear in court Tuesday.
Banda, who ruled Zambia between 2008 and 2011, is accused of corruption in the procurement of oil from a Nigerian firm.
Zambia's parliament earlier lifted Banda's immunity from prosecution, saying the move would allow officials to investigate cases of corruption during his rule.
Banda's lawyers say the accusations are part of an effort to weaken opposition parties by harassing and intimidating their leaders.
