The Department of State Services (DSS) has freed Salihu Tanko, a former media aide to the Kano State Governor, Abdullahi Ganduje.
Tanko was arrested on Friday after calling on President Muhammadu Buhari to check Nigeria’s worsening insecurity or resign.
He was sacked by Governor Ganduje shortly after his arrest.
Tanko’s father, Tanko Yakassai, confirmed to newsmen that he was released late Monday evening.
The elder politician said he was yet to be briefed on the alleged crime for which he was arrested and detained by the SSS.
Newsmen reported Tanko, on Twitter, saying the All Progressives Congress (APC) has failed Nigerians over the worsening insecurity.
Confirming Tanko’s arrest, the SSS spokesperson, Peter Afunnaya, in a short statement late Saturday in Abuja said he was in their custody, facing investigation.
“This is to confirm that Salihu Tanko-Yakasai is with the Department of State Services. He is being investigated over issues beyond the expression of opinions in the social media as wrongly alleged by sections of the public,” the statement said.
