Another body had been recovered from the rubble of a building that housed a school that had collapsed in the largest city in Nigeria, Lagos said, said rescue workers on Thursday.
"We've worked all night and a body has been recovered," said National Emergency Management Agency (NEMA) Southwest coordinator, Ibrahim Farinloye, to AFP.
The run-down building in the city's densely populated Lagos Island district came down without warning on Wednesday morning.
Locals, firefighters and other rescue workers searched the debris to find the prisoners in chaotic scenes.
Thirty-seven people were rescued alive, Farinloye said Wednesday night.
The Governor of Lagos, Akinwunmi Ambode, said the building was planned for demolition and a kindergarten and elementary school were being illegally operated on one of the floors.
School bags, toys, and clothing were under the rubble as a bulldozer tried to make his way through the wreckage.
Nearby shop worker Adeniyi Afolabi gave the name of the school as Ohen Nursery and Primary, saying that there were 144 students on Wednesday.
Another local, Zion Munachi, also confirmed the name and number of students. Both said that not all children were at school for physical activity.
Joshua Yang from the Lagos Fire Department said the nursery area of the building had been cleared.
"There are no people left in the rubble," he told TVC News.
Building collapses are tragically common in Nigeria, where building regulations are regularly flouted.
In September 2014, 116 people – including 84 South Africans – died when a six-story guesthouse collapsed in the Lagos church complex of the famous televangelist TB Joshua.
A request revealed that additional floors were added without a building permit.
In 2016, at least 60 people were killed when the roof in a church in Uyo, capital of the state of Akwa Ibom, collapsed in the south.
