An overheating courtroom heard the cold facts and figures of an audit report into corruption-accused former top cop Jackie Selebi's financial affairs on Monday.

Dean Friedman, a KPMG auditor, took the witness stand in the High Court in Johannesburg and began going over a forensic investigation report into Selebi's lifestyle, as well as the Spring Lights account.

Slain mining magnate Brett Kebble and his associate John Stratton allegedly used the bank account of a company called Spring Lights to send Selebi's former self-proclaimed friend Glenn Agliotti payments.

Agliotti, a convicted drug trafficker turned State witness, previously testified that he asked Kebble and Stratton for a $1-million "consultancy fee" for access to Selebi.

Friedman testified KPMG was involved in an "Empire K" investigation into the financial affairs of Kebble and Stratton's company JCI, when it was asked to investigate Selebi's financial affairs as well.

During this investigation, "we received information that there was something untoward in Spring Lights and it was explained that Glenn Agliotti was the man to contact".

During a meeting with Agliotti, the auditing team was referred to Kebble's ex-security head Clinton Nassiff.

Friedman said the audit looked into Selebi's cheque account and credit cards between 2004 and 2006. He said from January 2005, there was less expenditure in the cheque account. He said this could because Selebi was not spending less money, but had "other sources".

Friedman said "we were then referred to statements of Mr Agliotti in which he indicated cash payments to Mr Selebi".

The auditor, dressed in a black suit and speaking so softly he was almost inaudible to the public gallery, then turned to the report into the Spring Lights account.

The court heard about seven cash cheques taken from the Spring Lights account between June 2004 to September 2005 with values ranging from R10 000 to R200 000. One cheque for R30 000 was drawn on September 28, 2005. Kebble had been shot dead in his car in Melrose, Johannesburg, the previous night.

Agliotti was arrested for the murder in November 2006 and was set to go on trial next year.

Phone records apparently indicate Selebi was called from the scene of the crime.

Friedman said he went through counterfoils of cheques marked "JS", "Chief" and "c.o.p".

"John Stratton shares the same first initials as Selebi," he commented about the cheques initialled "JS".

As to the c.o.p cheques, "we assume that c.o.p may either mean cop or it could mean commissioner of police".

Friedman said the cheques marked "chief" were also included in their report through a suspicion they could be connected to Selebi.

"We understood from Mr Agliotti's affidavit that sometimes he made reference to Selebi as chief and on that basis that cheque was included."

Towards the end of proceedings, the broken airconditioning seemed to affect everyone in the room.

"I think the witness is struggling M'Lord. I think it is terribly hot," prosecutor Gerrie Nel said.

When Friedman indicated he was all right, Judge Meyer Joffe quipped: "If you are OK, you are the only one. I'm very hot."

The trial entered its fifth week on Monday.

Selebi faces a charge of corruption and another of defeating the ends of justice in connection with at least R1,2-million he allegedly received from Agliotti and others in return for favours.
