Former police chief Jackie Selebi's corruption conviction is a "true reflection of the proper administration of justice", the National Prosecuting Authority (NPA) said on Friday.

"We have presented a formidable case and there was diligent work," NPA spokesperson Mthunzi Mhaga said outside the Johannesburg High Court.

Selebi was found guilty of corruption but acquitted on a charge of defeating the ends of justice and will be sentenced on July 14.

He was released on a warning and ordered to report to court on that date.

The former Interpol president sat with his shoulders slumped as his lawyer Jaap Cilliers and state prosecutor Gerrie Nel discussed whether bail should be extended.

Nel said that because Selebi had been convicted of a schedule five offence he had no objection to bail being set.

Cilliers and Nel discussed Selebi's previous convictions. One was a R100 fine for damage to police property in 1974 and the other related to the possession of unlicensed firearms on his return from political exile in 1993.

Nel wearily packed his bags and said "no comment" after Selebi was convicted.

Before exiting court, reporters approached Selebi for comment but he refused.

"Nothing, nothing," he said.

In his judgment, Judge Meyer Joffe tore into Selebi and key witness Glen Agliotti, saying that both had shown a "habit of fabricating evidence and lying".

"There is a stigma in society about labelling a witness a liar... But that is what the accused did," Joffe said on the second day of his judgment.

"It is a finding that as head of the SAPS [SA Police Service]... he had a low moral fibre and cannot be relied upon."

Joffe said that Selebi had not set a good example for the SAPS during his time on the stand.

Joffe spent six hours on Thursday reading through evidence that had already been presented to court.

Selebi was facing charges of corruption relating to up to R1,2-million he allegedly received from various people in return for favours.

Earlier Joffe said that Agliotti, whose testimony the State relied on heavily for its case, had been an "untruthful" and "unreliable" witness in the trial.

"Agliotti can be described as one of the most untruthful and unreliable witnesses to testify in this court," Joffe said.

"Clearly Agliotti's evidence in court must be viewed with circumspection."

Joffe also dealt with meetings arranged by Agliotti between Selebi and the Kebble mining family.

Selebi insisted during the trial that he asked for meetings with businessmen Roger Kebble, Brett Kebble and Gavin Varejes and was not persuaded to attend these meetings by Agliotti.

The prosecution said that Selebi attended the meetings as a favour to Agliotti, who was alleged to have paid Selebi R1,2-million to grant an audience to his friends.

The prosecution claimed that Selebi helped Agliotti and his associates receive preferential and special service from the SAPS.

Selebi said that he met the Kebble family in 2004. "I demanded to have the meeting. For two years, Agliotti had wanted me to meet with them," he said.

He denied that he discussed police business with the Kebbles.

Joffe said it was inconceivable that the head of the SAPS would involve himself in the "political education of Kebble and his associates".

"The meetings were arranged by Agliotti," he said. "They were attended by Selebi not out of friendship, but out of necessity because Agliotti was paying him."

Joffe said that Selebi claimed he resisted meeting the Kebbles for two years.

"This evidence is clearly not true."

"It is inconceivable that the accused would be in the company of the Kebbles because he knew they were being monitored by the police.

"He is the highest officer in the SAPS... And in his testimony he said he was not naive."

Joffe said that Selebi had placed no evidence before the court to prove that he was being prosecuted because of his views on the closure of the elite crime fighting unit, the Scorpions.
