According to the Borno NSCDC commandant, Ibrahim Abdullahi, the book was discoveredduring an operation by men of the command at an abandoned house in Dikwa local government area of the state.

“It is sad that many innocent souls had been dragged into submitting to Boko Haram through spiritual indoctrination,” he said.

“The book, named`Guduma`, was used by the insurgents as a powerful charm to indoctrinate followers into submitting to the dictates of leaders of the sect.

“Our findings revealed that the book was also used in deceiving victims and members of the sect into believing that it could make them invisible and also offer protection against bullet shots and bombs.
