Officers of the Nigerian Police Force on Wednesday fired tear gas at students of University of Lagos (UNILAG).
The students had converged around the school to protest the increase in tuition.
The protest appeared peaceful until shots were fired by the police officers who were on ground to monitor the students.
The National Association of Nigerian Students had on Tuesday warned the Department of State Services not to prevent students from exercising their rights to protest, saying it is a universally recognised human right.
The National Public Relations Officer of the union, Giwa Temitope stated that the statement made by DSS on Monday that some politicians were mobilising student leaders for violent protest against the Federal Government over socioeconomic matters was propaganda.
He boasted that the protest would go on as planned.
