Four people have died while five others were injured when a one-storey building under construction collapsed on Wednesday at Flourmill Estate, Magbon, near Badagry, Lagos State.

A witness, Oluwagbenga Ogundele, told the News Agency of Nigeria (NAN) that the building collapsed on the nine construction workers on site at about 3p.m.

Ogundele, who works as security guard near the site, said that residents were alerted to the scene by a visitor to the site.

“The visitor was not in the building when it collapsed, it was him that called for assistance while policemen from Area ‘K’ came to rescue them.

“We were able to rescue five alive because they were calling for help, while four of them gave up the ghost.

“Police, Fire Brigade and our intervention saved those that survived,” the witness said.

The five injured labourers were taking to Catholic Church Hospital, Magbon, while the four dead bodies had been deposited at Badagry General Hospital mortuary.

One of the elders in the Estate who spoke on condition of anonymity said that the building had been abandoned by the owner for close to six years before work resumed on it recently.

“It was recently that a new owner started building another floor on top to make it a storey building.

“About 3p.m., we had a loud sound and when we got to the scene, the building had collapsed on the labourers working inside it,” he said.

Mr. Ibrahim Farinloye, South-West Coordinator, National Emergency Management Agency (NEMA) confirmed the incident.

Farinloye said that four persons died while five sustained injuries during the collapse.

The Lagos State Fire and Rescue Service, Badagry Station also confirmed that five victims were rescued with varying degrees of injury.

Officials of the Lagos State Building Agency (LABCA) have sealed up the premises of the collapsed building.
