An architect involved in the construction of Huruma residential building, which collapsed in the Kenyan capital of Nairobi killing five people, has been arrested.
Police have not named the person being questioned but said they are also investigating engineers who worked on the project.
Police CID director Ndegwa Muhoro said his officers are also still looking for the female owners of the building.
He said: “Let them surrender to the police wherever they are. They are needed to answer many issues regarding the killer house.”
Search and rescue missions at the building ended on Tuesday with five people confirmed dead.
Nairobi Governor Evans Kidero has suspended 18 officials following the collapse of the building on Sunday night.
They are from housing and planning department. Kidero said he took action after preliminary findings showed the officials had “failed to enforce the law”.
Among those suspended are Rose Muema, chief planning officer, Jairus Kathenge, who is the director of enforcement and compliance as well as 16 other officials.
Residents said they had seen cracks on the floors of the building even before they went for their Christmas holidays.
Tenant Irene Muthe said she had decided to move her family from the building after the festive season.
She said: “When I came back, I decided to go look for another house to rent. On Sunday, I took my two children to my sister’s house and I went with my husband to look at a house that we had found in Pangani.
“We delayed there because we liked the house and we had to clear with the landlord. As we were returning, a neighbour called me and said that the house had collapsed,”
Two of the survivors are still in hospital with multiple injuries.
