Fifty persons have so far been rescued from the collapsed building at Ita-Faji, Lagos Island, the Lagos State Emergency Management Agency (LASEMA) has said.
Tiamiyu Adesina, LASEMA General manager, made this known at the scene of the collapse.
He added that the rescue team would remain on the scene until they can confirm that no one is left under the debris.
Rescue operation was put on hold for a few minutes when it was discovered that there was still power supply in one of the electric poles beside the building.
The operation has since resumed.
