Johannesburg - Czech businessman Radovan Krejcir was arrested on charges of attempted murder and kidnapping on Friday, Eyewitness News reported.
According to the report, the details were sketchy.
Hawks spokesman Captain Paul Ramaloko told Sapa he was not aware of the arrest, but would try and find out about it. Gauteng police referred all questions to the Hawks.
Last Tuesday, two people died and five were injured in an explosion at Krejcir's business, Money Point, in Befordview, on the East Rand.
In July, Krejcir was the target of an apparent assassination attempt outside Money Point.
Moments after he got out of his car, a remote-controlled gun installed behind the number plate of a car parked near his fired at him. Krejcir escaped unharmed.
The SA Revenue Service said last Friday that all Krejcir's assets had been placed under the control of a curator.
