JOHANNESBURG - Gauteng Premier Panyaza Lesufi says an investigation into the Joburg explosion is now the subject of a Department of Labour investigation.
Two people remain in a critical condition following the explosion in the Johannesburg CBD.
One person has died and has been identified through fingerprints.
Lesufi says a preliminary report indicates that there may be similarities to an incident that occurred in Yeoville back in 2010.
Two people were injured in a Telkom building in Yeoville when gas exploded.
"The Department of Labour indicates the nature of gas when it explodes and what has happened here its similar to what happened at Yeoville what is known as Telkom towers," Lesufi said.
"They claim that there are similarities."
Meanwhile, Transport Minister Sindisiwe Chikunga says her department will engage Santaco to assess the extent of the damage.
The explosion tore open roads and flipped vehicles, damaging minibus taxis.
“We definitely want to engage what damage was caused," she said.
