The Commissioner for Lands and Housing in Oyo State, Mr Olusegun Olayiwola, says the state government will investigate the cause of the collapse of a four-story building in the Bodija area of Ibadan that occurred on Thursday morning.

Olayiwola said this when he led some government functionaries to the scene of the incident.

He said erring persons or persons would be fully sanctioned after investigation, to serve as a deterrent to others.

Speaking with newsmen during the inspection, the commissioner observed that substandard materials were used for the construction.

He noted that the land allocated for the building project was not suitable for the kind of structure being built.

Olayiwola added that the contractor handling the project failed to follow established procedures for constructing buildings in the state.

The commissioner promised to present the Ministry’s findings to the deputy governor for necessary action.

He, however, enjoined developers in the state to always engage the services of professionals whenever they wanted to construct buildings, in order to avoid disaster.

The News Agency of Nigeria (NAN) reports that the structure under construction collapsed in the early hours of Thursday, leaving at least seven persons injured.(NAN)
