Pupils of Babs Fafunwa Millennium Secondary School took to the streets on Wednesday to protest the death of their mates.
An articulated truck crushed many pupils on their way home from the school on Tuesday.
The exact number of those who died remains conflicting, but eyewitnesses said no fewer than 17 were crushed or severely injured.
The accident occurred at the Grammar School Bus Stop, Ogunnusi Road, along Ogba-Ojodu/Berger axis.
The truck driver was said to have been trying to evade arrest by Vehicle Inspection Officers (VIO) and men of the Lagos State Transport Management Agency (LASTMA) from Berger Division, Ikeja when he rammed into the pupils.
Parents on Wednesday stormed the school in protest.
Others demanded to take their children and wards home.
Some said the school should not have opened Wednesday.
Commissioner for Education, Mrs. Folashade Adefisayo, addressed them in a bid to calm the tensed situation.
She said the safety of the pupils was paramount.
The pupils were eventually allowed to go home, but they took to the streets in protest.
