Details of former police chief Jackie Selebi's financial affairs were revealed during his corruption trial on Tuesday by a forensic auditor.

In his two-day stint on the stand, KPMG auditor Dean Friedman told the High Court in Johannesburg of Selebi's spending patterns in his credit card and cheque accounts, as detailed in a report on his financial affairs.

Friedman said that "inferences" could be drawn from the fact that Selebi's expenditure on his cheque account and credit cards dropped in 2005.

This meant Selebi landed up keeping large amounts of cash in a low interest-bearing account in 2005.

"One can infer a number of things. Mr Selebi might not have been financially as astute, which clearly is a criticism of his financial management. Or that there was such a flow of cash. If you have a lot of cash that becomes available, as has been alleged with Mr Selebi, then... an inference... can be drawn."

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 convicted drug trafficker Glenn Agliotti and others in return for favours from 2000 to 2006.

However, during cross-examination, defence lawyer Jaap Cilliers put it to Friedman that rather than a drop in expenditure in 2005, Selebi might have spent particularly high amounts in the months preceding.

Cilliers said this was due to household renovations and tuition fees that Selebi paid out.

"It's not a situation where you have a dramatic downfall in payments of the account. Rather it's where you have an upsurge in the payments [in the period] preceding it," Cilliers said.

He then detailed cheque payments made out to companies with names which Friedman agreed had "characteristics of those involved in house building".

Cilliers also referred to cheques made out from Selebi's account to Rosebank College and the University of Johannesburg.

The court heard that Selebi's wife Anne was in charge of their household's accounts.

"Mrs Selebi was in complete control of all [financial] affairs. Mr Selebi was not the kind of person who involved himself in all these issues," said Cilliers.

During cross-examination on Tuesday, Cilliers put it to Friedman that neither the KPMG report nor his evidence showed any unexplained cash payments or credit cards going into Selebi's account.

"You could find no cash that could not be explained from the legitimate earnings for the accused. There was no cash that you could not find the source of."

Friedman replied: "Yes, there is none."

Friedman also testified about the bank account of a company called Spring Lights which, it has been alleged, was used by slain mining magnate Brett Kebble and his associate John Stratton to send Selebi's former friend Agliotti payments.

Agliotti, who has turned State witness, previously testified he had asked Kebble and Stratton for a $1-million "consultancy fee" for access to Selebi.

On Monday, Friedman told the court about seven cash cheques that were drawn from the Spring Lights account between 2004 and 2005, some marked on counterfoils with a reference to 'JS', Chief and c.o.p.

On Tuesday morning, a woman in the public gallery disrupted court asking to see Selebi's lawyer.

"May I disturb the court? I'd like to see Jackie Selebi's lawyer immediately," the woman, dressed in a green dress, said.

She was taken out of court and Cilliers later told Judge Meyer Joffe she was "totally incoherent".
