Johannesburg - Public Protector Thuli Madonsela will react fully to a report that police plan to arrest her at a scheduled, unrelated media briefing at noon on Wednesday, her spokesperson said.
"We will not be commenting until the media briefing at 12," said Kgalalelo Masibi.
"We only became aware of it after The Star media inquiry yesterday," she said, when asked whether she knew of Madonsela's reported pending arrest.
According to an advisory, Madonsela was scheduled to address the National Press Club in Pretoria on Wednesday about an investigation into the alleged improper soliciting of business for donations to the ANC and other issues.
Her office has been investigating processes followed relating to leases for police headquarters in Pretoria and in Durban.
In February, she announced that the R500m Middestad Building lease in Pretoria was signed unlawfully and she said the accounting officer, who she named as police chief General Bheki Cele, was among those responsible.
She also criticised Public Works Minister Gwen Mahlangu for going ahead with the deal in spite of legal advice suggesting otherwise.
Businessman Roux Shabangu was the owner of both buildings.
Police would not comment on The Star report on Wednesday.
"We are not going to be drawn into comments attributed to faceless people," said Colonel Vishnu Naidoo.
The Star reported that police planned to arrest Madonsela on charges of fraud and corruption.
His colleague Brigadier Sally de Beer confirmed that this was the police's position on the report.
Hawks spokesperson McIntosh Polela was not immediately available to comment.
National Prosecuting Authority spokesperson advocate Mthunzi Mhaga said early on Wednesday that he was not aware of charges pending against Madonsela.
Earlier, in an interview on SAFM, Police Minister Nathi Mthethwa said he was surprised at the news.
Madonsela, who was interviewed shortly after Mthethwa, denied involvement in any corrupt activities while working for the SALRC.
