A former National Chairman of the Peoples Democratic Party (PDP), Ali Modu Sheriff has offered himself for investigation over his alleged sponsorship of the Boko Haram sect.

The Borno State Attorney General and Commissioner for Justice, Kaka Shehu Lawal, had, at the Nigerian Bar Association (NBA) conference in Port Harcourt on Tuesday, accused Sheriff of being a major sponsor of the insurgents.

But Sheriff, in a reaction by his Media Adviser, Inuwa Bwala on Thursday, rejected Lawal’s allegation, demanding a retraction and apology from the Borno Attorney General.

To prove his innocence, Sheriff has called for comprehensive investigation aimed at exposing sponsors of the terror group.
