A building that collapsed in Roodepoort, killing two, was not registered with the labour department, SABC reported on Saturday.

"What we have determined up until now is that the contractor did not inform the department that construction was taking place here," said labour department investigator Kenny Fick.

This means health and safety checks at the site would not have been done by the department.

Fick said the department would be investigating the cause of the accident in the next few days.

" We need to talk to the inspectors and the Joburg Metro to determine what they've done, and how this plan was approved, and that we'll be doing in the coming week."

SABC also said a demolition expert will be called in to accurately assess what remains of the building.

The department apparently hopes to flatten it.

On Saturday, the body of a man was discovered in the rubble of the collapsed Little Falls office block under construction.

Police spokesperson Inspector Karen Jacobs said the body was discovered around 9.30am.

Johannesburg Emergency Services spokesperson Percy Morokane identified the body as belonging to 25-year-old Artur Nombora from Myembane province in Mozambique.

One other person was killed and fourteen were injured in the building collapse.

Nombora's brother, Jorge Magerizane, told the SABC on Saturday: "I’m hurting. My brother's body must now go back home, and we don't have money to transport him.

"Maybe the South African government can help us."
