He gave further insight into his relationship with the dreaded Islamist sect and reiterated his denial that Bama was arrested in his Maiduguri home.
He told his interrogators that he gave N1.5 million for Sallah rams to the sect members following their threat to attack him.
He explained that when they took his aide to his house for a search, they retrieved N250, 000 and left a message with the aide for him that he should provide them N10 million or they would come for him.
