Four men have been arrested in connection with what could be one of South Africa's biggest cash heists.
Sowetan reported yesterday that armed robbers stormed the Coin Security Group building in Modderfontein and made off with cash that could amount to between R50million and R100million on Saturday.
Talk Radio 702 said that about R150 million had been stored at the depot at the time of the heist.
An armed gang disguised as Coin Security guards stormed the company's offices at about 5pm on Saturday and stole boxes containing the money.
Johan Burger, of the Institute of Security Studies, told Sowetan yesterday: "This robbery happened too smoothly.
"It could only have been an inside job, meaning the robbers either got information from an insider or an employee was directly involved."
