ABUJA, Nigeria (AP) — Nigeria’s House of Representatives voted Friday to remove a lawmaker from a probe into the country’s mismanaged fuel subsidy program over allegations that he took a bribe from an oil company.

Rep. Farouk Lawan of the country’s ruling People’s Democratic Party missed the hearing in Nigeria’s capital, as police detained him the night before for questioning over an alleged $620,000 bribe paid by an oil company owner who has ties to President Goodluck Jonathan. Lawmakers unanimously voted to suspend Lawan from the probe and begin investigations into the actions of a legislative staffer.
