The collapse is being investigated.

The main hall of a newly constructed school in Ejigbo, Osun State, collapsed Wednesday morning leaving at least two people injured.

According to witnesses, at about 6 a.m., a loud bang was heard, then the roof of the main hall suddenly collapsed.

The state government released a statement saying investigation was underway to ascertain the cause of the collapse.

It, however, noted that all necessary safety and quality assurance tests were conducted by experts and the building was certified safe.

“As a responsible government, it is too early for us to say what the exact cause of the collapse is until we have full investigations and advice of professionals,” said media aide to the governor, Semiu Okanlawon. “However, it must be stated here that all necessary quality assurance tests were carried out to ensure structural durability and integrity of the project just as in all other projects under this administration. “Engineers from the Osun Ministry of Works and engineers from the Structural Engineering section of the Nigerian Society of Engineers have been dispatched to the site to establish the real cause of this unfortunate incident.”
