Recovering from surgery, the 27-year-old athlete revealed that his attackers spoke a language that he did not understand.
"It was a funny language. I didn’t hear the words. They were not speaking isiZulu," he told the media outlet from his bed at Durban's Netcare St Augustine's Hospital.
"I didn’t understand [them] but I am still confused."
Despite having few details to offer on the attackers' words, Gwala was able to describe their actions.
"They cut me and then the one who was cutting stopped and then he went to look [at something]. I don’t know what he was checking. But then he came back and said [to the others] - let's go - and then they ran away."
A friend of mine, cycling in the Durban area was robbed by three people this morning, Then they attempted to saw off both legs with a chainsaw. Blade too blunt and only got half way through one and started on the other. Absolutely disgusting! How safe are we on SA roads?— Henri Schoeman (@H_Schoeman) 6 March 2018
Gwala crawled along the road
Badly injured, Gwala lay on the roadside and managed to reach his phone to try to contact the police.
"The police didn’t respond. Then I decided that I had to crawl with this one leg to the road.
"Some security guards [from Fidelity Security Regional] stopped their cars and I told the guy - take me to hospital.
"They took me straight to Albert Luthuli Hospital."
Later on, he was transferred to Netcare St. Augustine’s Hospital, where he underwent surgery.
According to police spokesperson Captain Nqobile Gwala, investigations into the incident are taking place.
