The Department of State Services (DSS) has clamped down on associates of the embattled bandits’ negotiator, Tukur Mamu, arresting his father-in-law, Abdullahi Mashi, Thursday night.
According to Daily Trust, operatives of the secret police also visited the house of Mamu’s brother-in-law, Ibrahim Tinja, who was arrested and deported with the Desert Herald Publisher on Wednesday.
Mamu and four members of his family were arrested at the Mallam Aminu Kano International Airport on Wednesday after they were deported from Egypt on the request of Nigeria’s intelligence agencies.
The publisher was said to be travelling to Saudi Arabia for lesser hajj together with his two wives, his eldest son, Faisal Mamu and brother-in-law, Ibrahim Tinja.
While Mamu’s wives have been released, the publisher, his son and brother-in-law are still in custody.
The secret police had on Thursday raided the residence and office of the media practitioner who negotiated between the terrorists who kidnapped Abuja-Kaduna train passengers on March 28 and the families of the victims.
