The International police, Interpol, on Tuesday, quizzed the Abuja-Kaduna train hostage negotiator, Tukur Mamu, and detained him at the Cairo International Airport.
He was arrested while awaiting a connecting flight to Saudi Arabia.
It was gathered that Mamu has been released to the Department of State Security (DSS) and he is on his way to Nigeria.
Mamu, the Publisher of Desert Herald Newspaper in Kaduna who worked for the release of the majority of March 28, 2022, Kaduna Train, was with his two wives and one other person when he was quizzed.
According to reports he was released the next day and taken back to Nigeria by Interpol after he was interrogated and nothing incriminating was found against him.
It was gathered that Mamu is expected to arrive at Aminu Kano International Airport in Kano, Wednesday, and may be handed over to the officials of the Department of State Security (DSS), in Nigeria.
Recall that Mr Mamu had in the heat of the negotiation backed down from the negotiation arrangement due to what he described as a threat to his life by the federal government.
Many of the victims are still being held by the terrorists in their camps.
