The JSE has fired Ntuthuko Shoba, the alleged mastermind of the murder of his heavily pregnant lover Tshegofatso Pule.
JSE confirmed on Friday that Ntuthuko Shoba is no longer their employee.
The JSE assisted the SAPS in their investigation and it will continue to fully co-operate with the investigative authorities if and when required to do so.
It was also reported that Shoba was employed as an analyst at the stock exchange.
He was arrested in February after his alleged accomplice Muzikayise Malephane, who confessed to killing Pule, turned state witness.
