A Nigerian anti-corruption agency is investigating allegations that former ministers took bribes from German technology firm Siemens.
This follows October's court decision in Munich where Siemens was found guilty of paying bribes to secure contracts and agreed to pay a fine of ?201 million (£144 million).
The court ruling said a former manager bribed public officials in Nigeria, Libya and Russia in 77 cases between 2001 and 2004. The Nigerian ministers are among those that maintain their innocence.
Nigeria-based Independent Corrupt Practices and Other Related Offences Commission is questioning officials about the scandal. It has also approached Interpol for help with the investigation.
The adviser to Nigeria's president Umaru Yar'Adua issued a statement that said "in this Siemens scandal, as in all cases that border on good governance and transparency, there will neither be sacred cows nor a cover up for anybody found culpable of breaching the law."
After the trial, Siemens said it accepted full responsibility for the matter.
