Czech businessman Radovan Krejcir and an associate will appear in the Alberton Magistrate's Court on Monday, national police commissioner Riah Phiyega said on Saturday.
“We will be in court on Monday and should there be an application for bail, we shall oppose it,” she told reporters in Pretoria.
“We will also be looking at any involvement of our own members.”
The name of Krejcir's associate, who was arrested with him on Friday, would only be disclosed in court.
In a statement issued on Friday, the police said that although they did not usually name suspects before they appeared in court, “it was decided on the basis of the existence of an arrest warrant and public interest that the suspect (Krejcir) in this instance will be identified”.
On Friday, police said Krejcir had been arrested on charges of attempted murder and kidnapping.
However, Phiyega on Saturday said he was arrested on charges of kidnapping and assault with intent to cause grievous bodily harm.
Pressed for further particulars, Phiyega said she did not want to prejudice the State's case.
She also would not mention the details of the complainant, other than saying “it's a South African male”.
Phiyega said the assault happened in June. -Sapa
