The National Association of Nigerian Students (NANS) issued a 48-hour ultimatum to the police for the unconditional release of the arrested student.
The national treasurer of NANS and the chairman in charge of North West, Bashir Sulaiman Limanci, at a press briefing in Dutse, Jigawa State capital, condemned the arrest and detention of Adamu who is to start his final examination on December 6.
The students threatened to convoke a nationwide protest against the police and Mrs Buhari.
Meanwhile, the management of FUD has said the university was not in session when the incident happened, thus, the student was not under their care when he made the post on Twitter.
“The unfortunate incident involving Aminu Adamu, who made a Twitter post, happened during the break. He did the posting in his capacity as Aminu Adamu, not as a student of FUD.
“He was trailed to Dutse where he was arrested. The university authorities have spoken to the parents who have already engaged the services of a lawyer to handle the matter and they are hopeful for an amicable resolution soon,” the university’s spokesperson, Abdullahi Bello, said in a statement.
