According to Eyewitness News, shots were fired at Krejcir outside his office near Eastgate. Krejcir said a remote-control-triggered gun with 12 barrels was used.
The weapon was attached to a red Volkswagen Polo, which burst into flames after firing.
Krejcir, who arrived in South Africa in 2007 on a passport bearing the name Egbert Jules Savy, is a controversial character. He was picked up on an Interpol red notice by South African authorities because he was wanted for tax fraud and other offences in his native Czech Republic.
He has since been convicted in absentia on some of these charges.
His associates, including bouncer boss Cyril Beeka and strip-club owner Lolly Jackson, also have the nasty habit of turning up dead.
