Johannesburg - A second body was found on Thursday in a collapsed building in Power Park, Soweto, Johannesburg emergency management services said.
“Rescue workers are trying to remove him from the rubble,” spokeswoman Nana Radebe said.
The man's body was found beneath the rubble around 3pm on Thursday afternoon.
Another man was killed on Wednesday night after the building, an old power station behind the Orlando towers, collapsed on Wednesday.
On Thursday morning, a man's arm was amputated before he could be rescued.
“The man was taken out after 3am, and it was difficult for the trauma doctors to access him so we had to gain access from under the site,” Radebe said.
“His arm was amputated while he was still trapped because we could not move the building from his hand, because it could destabilise the area and cause a secondary collapse.”
He was pinned to the ground by a beam on his hand. The rescue team had to remove metal, beams, and concrete to help him. He was taken to hospital in a stable but critical condition, she said.
Radebe said more specialised equipment, such as hydraulics, were brought to the scene to help the rescue technicians.
On Wednesday, Radebe said paramedics received a call from an injured man who claimed to have been part of a group allegedly trying to steal cables and metal from the building.
