A witness at the scene of the disaster said that ambulances were seen taking people out of the collapsed building to the Isolo General Hospital.
The church authority is yet to make official statement on the matter. It has also failed in the confirmation of the number of casualties.
Policemen and LASTMA officials were on ground to disperse the crowds, who were gathered outside the gate of the collapsed structure.
The said building, which usually serves as a guest house for some foreigners and people from the neighbouring African countries, was completed four months ago.
A source said that the building was formerly a four-storey building, but got converted to six-storey building to accommodate more of its visitors.
Also at the scene were personnel of the Lagos State Emergency Management Agency, National Emergency Management Agency and the Nigerian Security and Civil Defence Corps were also on the ground.
LASEMA officials were however denied access into the premises of the church while journalists were also chased away from the scene of the incidence.
