The Public Relations Officer of the Service, Francis Enobore, told the News Agency of Nigeria (NAN) on Saturday that there was an “incident” at the prison on Friday night.
He however added that it had nothing to do with Charles Okah.
“We are yet to find out if any inmate escaped or not.
“However reports making the rounds that Charles Okah, the leader of the Movement for the Emancipation of Niger Delta (MEND) escaped during the jailbreak is false.
“Yes there was an incident yesterday, but Okah was not involved; he is still in custody.
“I have been in touch with our men in the prison facility and there is nothing like that,” Enobore said.
He said that the Controller of Prisons had ordered an investigation into the matter.
“We want to know if anybody escaped and if yes, what are their identities.
“We will release a statement once the preliminary investigation is concluded,” the PRO said.
