Selebi pleaded not guilty to charges of corruption and defeating the ends of justice when the trial started more than a month ago.
This week a couple of number crunchers, several policemen, a reservist and even a golf course manager stepped into the witness box. They followed druglord and murder accused Glenn Agliotti's former fiancée, Dianne Muller, and her father, Martin Flint, who testified about payments to Selebi.
The court has heard from more than one witness that Agliotti paid large sums of cash to Selebi and that Selebi lived beyond his official income.
After analysing Selebi's finances between 2004 and 2006, KPMG forensic auditor Déan Friedman said Selebi had kept a high balance in a low interest bearing account and there was noticeably less spending from his cheque account from January 2005 onwards - at the height of his friendship with Agliotti.
Yet, at the same time, the forensic investigation indicated Selebi was spending more than he earned, that he kept large amounts of cash, and had other sources of finance.
In the 11 days he was on the stand, Agliotti gave detailed evidence about paying Selebi more than R1-million, but remained adamant that the payments were not bribes, as he received nothing in return, he said.
But this week the court heard that Selebi had favoured his friend. Police reservist Aubrey Shlugman, who had responded to an armed robbery involving one of Agliotti's friends, testified that Selebi told him to take care of his "friend", Agliotti.
The court also heard that Selebi had warned Agliotti that British police were monitoring his activities.
Commissioner Mark Hankel, the police's information manager, told the court a file containing a copy of the British report Agliotti is alleged to have been shown by Selebi could not be found to this day.
The case continues on Tuesday.
