The building that housed classrooms and offices collapsed on Friday while the students were writing their third-term examination.
Mr Umejuru cautioned property developers against constructing buildings without approval from relevant authorities.
“Twenty-five people were rescued from the site when the building went down on Wednesday. They are all doing fine.
‘‘Once you have laws that approve minimum standards in housing, then you can implement them to ensure the quality of houses you want,” the NIOB president stated.
The state building control agency had in 2021 sealed off the site twice for flouting building regulations.
