In Kano on Tuesday, some students of Maitama Sule University, protested against her arrest and continue detention.
The students, who marched from the temporary site of the University to Government House, Kano and later trekked to the Saudi Arabia Consulate at Ahmadu Bello Way, Kano, called for her immediate release.
The students who carried placards with various inscriptions, called on Saudi authorities to release the student in view of the fact that preliminary investigation had exonarated her from committing the offence.
Speaking to newsmen, the students’ spokesman, Sama’ila Auwal, said the decision to protest the arrest of Aliyu was borne out of the investigation carried out by the National Drug Law Enforcement Agency (NDLEA) which indicated that their colleagues was innocent.
“We want Saudi authorities to consider the investigation conducted by NDLEA which revealed that she was innocent because a drug syndicate at Malam Aminu Kano International Airport tagged a bag with her name.
“We need Justice for Zainab, we want her released hence our decision to stage the peaceful protest to show our concern over the matter,”Auwal said.

He urged the students to remain calm as the Federal Government was doing everything possible to secure her release.
According to him, the state government was also concerned over the plight of Aliyu who had also been exonerated from the case.
At the Saudi Arabia Consulate, two students were selected to meet with the Consular.
