service, said it was necessary for Mr Mamu to be detained for 60 days pending the conclusion of investigation of various acts of terrorism against him.
It alleged that the investigation established act of terrorism financing against the former terrorists’ negotiator.
It alleged that Mr Mamu, “the self acclaimed Kaduna train negotiator exploit the opportunity to perpetrate, aid and abets as well as render support to both local and international terrorist organisations,” among others.
The SSS had warned Nigerians over making comments on its arrest of Mr Mamu.
The SSS, in a statement by its spokesman, Peter Afunaya, asked the public to leave the agency alone and allow it to concentrate on the investigations which it said the outcomes had been “mind boggling.”
This came hours after the Islamic cleric, Sheik Gumi, to whom Mr Mamu is an aide, had faulted the arrest of the negotiator.
Mr Gumi, at a religious gathering on a Friday in Kaduna, had asked the security agency to charge Mr Mamu to court if it had any evidence against him, rather than keeping him in custody.
