Many workers are feared trapped in a 21-storey building under construction which collapsed on Gerard Road, Ikoyi, Lagos on Monday.
An eyewitness told the News Agency of Nigeria (NAN) on condition of anonymity that the building collapsed around 2.30 p.m.
The witness, who is also a worker on site, said that five dead bodies were seen at the top of the rubbles of the collapsed building.
He added that two persons had so far been rescued alive.
NAN also saw two bodies being removed away from the rubbles shortly before emergency responders, comprising Lagos State Emergency Management Agency, National Emergency Management Agency and Lagos Building Control Agency arrived at the building site.
As of 4.50 p.m., no official rescue operation had begun.
NAN reports that angry youths and some of the workers were seen doing the little they could.
Excavators from the relevant agencies were still been awaited as at 5.45 p.m. while crowd control remained a challenge at the scene. (NAN)
