The association's spokesperson Bonny Ndjishe denied this, saying Mathibela was merely one of their members and not in charge.
"Mata is controlled by the executive, and Mata collects money for the association. These are just allegations that people are making,"
A taxi owner who spoke on condition of anonymity confirmed having paid "protection money" to Vusi's people.
"I'm even scared to even talk about that man, he's the most dangerous person I know.
"He charges protection money from anyone including the Pakistanis and us, taxi owners," he said.
The taxi owner added: "If Vusi's people come looking for money, the best thing to do is to give them the money to avoid any trouble."
Vusi "Khekhe" Mathibela, also known as Nyawane, because he walks with a limp, grew up in Mamelodi East.
According to those who know him from way back, Mathibela dropped out of high school to become a taxi driver. He rose through the ranks and now owns more than a dozen taxis.
His late father was also a prominent taxi owner. The Mamelodi Amalgamated Taxi Association (Mata) confirmed this week that the Mathibela family still owned taxis and belonged to the association.
Mathibela, a nightclub owner, is a powerful young businessman who is already listed as a director of four companies.
Although only 32 years old, he has already resigned as director from four other companies, according to company records.
He was photographed with Floyd "Money" Mayweather during the superstar boxer's 2014 visit to SA.
