They were inside their homes when they suddenly heard a loud crack only to rush out from their houses to see that a building that is under construction, had collapsed.

The three-storey building was located near Imo Foundation and Imo Specialist Hospital, Umuguma, in the Owerri metropolis.

Several people were said to be trapped in the debris and no rescue effort has been made at the time of filing the report.

A resident of the area, said: "We just heard a loud noise and we quickly came out. We saw that it was the house under construction had collapsed. It sank to the ground, leaving the roof on top of the rubble.

“I have been hearing about collapsed building, but this one is incredible.’’

Asked if people were staying or living there, she said, “We know that people do stay there, but we don’t know whether people were there or not as of the time the building collapsed.”

Another resident, who spoke on condition of anonymity, said, “We heard that some people were trapped there, but we cannot verify it as rescue has not started.’’

The state police command has not made comments about the incident.

Building collapse is increasing in Nigeria and the Building Collapse Prevention Guild has blamed high quantity of metal scraps in construction steel for such incidents.

The National President of the guild, Mr Kunle Awobodu, made the observation at a seminar organised in Lagos by the Ikorodu Unit of the guild for steel manufacturers and other stakeholders in building.
