Two bodies were retrieved from a sewerage pit behind the Table Bay Hotel last night (Tuesday 5 January).
City of Cape Town's fire and rescue services spokesperson Jermaine Carelse says they were alerted to the incident at the V&A Waterfront at 18:18.
Two maintenance workers were stuck in the pit at East Pier Road.
"Several City resources, including Epping Training's Hazmat Response team, Spilltech and ER24 were dispatched to the scene.
"Because the area where the bodies were situated, was filled with toxic gasses, the team had to don Class B suits.
"They were hooked onto an airline and lowered into the pit by a rope system. The first body was retrieved at 22:23 and the second just after midnight (Wednesday 6 January)," says Carelse.
Carelse adds that the scene was then handed over to the police for further investigation.
