"We knew to look in this spot [the area where the deceased was found] because they hit the very same place three times in December‚" a spokesperson said.
The spokesperson added that the cable had been buried to keep the copper from being stolen.
"We deal with this on a daily basis. Now a man has been killed and another one is in hospital."
The severely injured alleged thief was taken to South Rand Hospital.
A bystander who asked not to be named described the gruesome scene: "This guy just sat in agony on the pavement – his whole body burnt – even on his head. His white skin was all black and pulled together in clumps‚ leaving pink flesh behind.
"Yoh‚ but I actually feel bad for this one [the injured man]. He looked in so much pain. His friend was just dead."
Local authorities were investigating.
