The Department of State Services (DSS) has confirmed the detention of the self acclaimed Kaduna train hostage negotiator, Mr Tukur Mamu.

Dr Peter Afunanya, the Public Relations Officer of DSS said this in a statement on Wednesday in Abuja.

He said the clarification followed series of enquires in respect of the arrest or otherwise of Mamu.

“This is to confirm that Mamu, as a person of interest, was intercepted by Nigeria’s foreign partners at Cairo, Egypt on Tuesday while on his way to Saudi Arabia.

“He was returned to the country on Wednesday and had been taken into the Service’s custody,” he said.

Afunanya said the arrest followed a request by Nigeria’s Military, Law Enforcement and Intelligence Community to their foreign partners to bring back Mamu to the country.

He said the request was for him to answer critical questions on ongoing investigations relating to some security matters in parts of the country.

The DSS spokesman sad the law would appropriately take its course in the matter.
