Ten persons, including four pupils, were feared dead on Wednesday following the collapse of a building on No. 63 Massey Street, Ita Faaji area of Lagos Island.
About 50 other persons had been pulled out of the rubble alive as of the time of going to press.
Rescue equipment from the Lagos State Emergency Management Agency had been deployed in the site.
Other emergency responders such as the Lagos State Ambulance Service, Lagos State Fire Service, Lagos State Building Control Agency, Federal Fire Service, National Emergency Management Agency, Nigeria Police Force, Rapid Response Squad, Nigeria Security and Civil Defence Corps, Nigeria Red Cross Society and the Lagos State Neighbourhood and
Safety Corps were also present.
A resident of the area, identified simply as Iya Segun, said the building collapsed as a result of its dilapidated state, alleging that government officials responsible for inspecting and certifying buildings for habitation had always turned a blind eye after being bribed by the owners.
The son of the owner of the building, Erinoluwa Akinmoladun, said the house was under the management of a developer, whom he identified only as Mr Giwa.
He said the construction of the building was completed in 2010 by the developer, who was supposed to manage it for 10 years.
Erinoluwa, who was at the scene assisting rescue workers, added that his father had been rescued, but was not sure if all his siblings had been pulled out from the debris.
When our correspondent visited the Lagos Island General Hospital, no fewer than four pupils were brought in dead and 42 names were made available by the management as those rescued and responding to treatment.
A mother of three, identified simply as Iya Sukura, whose children attend the school, said two were in critical conditions, while her first daughter was still trapped.
