- The manager of the Nigeria Agip Oil Company, a subsidiary of ENI Nigeria, was abducted by armed militants in Niger Delta State on Wednesday morning.
In a statement, the oil company said Feyi Dienye was abducted outside his home as he was on his way to work.
His driver who was shot during the abduction has been admitted at the ENI medical clinic in Port Harcourt.
ENI officials said they are cooperating with local authorities to rescue Dienye.
The abduction emerged as the Nigerian government and the oil-rich Niger Delta militants squabble over the affairs of an extradited leader of the Movement for the Emancipation of the Niger Delta (MEND), Henry Okah.
Nigerian President Umaru Yar'Adua refuted the rebel claims that Okah died in police custody.
But MEND said if their leader is alive, then the government should allow his family members, lawyers and doctors to have access to him.
After his extradition from Angola last week on arms deal, Okah is yet to appear in court.
The group had earlier given the government 24 hours to confirm or deny Okah's alleged killing by government soldiers.
Presidential Spokesman Segun Adeniyi has denied the rebels' claim that Okah died of gunshot wounds at a hospital in Kaduna.
MEND officials have threatened violent attacks on state institutions in the country, particularly in Niger Delta.
