The General Manager of the Lagos State Building Control Agency (LASBCA), Gbolahan Oki, said on Monday night the owner of the collapsed 21-storey building in Ikoyi area of the state got the approval to construct only 15 floors.

In a chat with journalists shortly after the incident, Oki said the owner of the property had been arrested and would be prosecuted over the loss of lives in the incident.

At least four persons died and several others trapped in the rubble when the building which was located along Gerard Road in Ikoyi came down Monday afternoon.

The LASBCA chief said: ” He got an approval for a 15-storey building but he exceeded his limit. I am on ground here and the materials he used are so inferior and terrible.”

The materials he used and the reinforcement are so terrible. He got approval for 15 floors but built 21.”
