Johannesburg - Captain Bongani Gininda on Tuesday concluded giving evidence in the trial-within-a-trial of Czech fugitive Radovan Krejcir and five others.
Gininda was urged in the High Court in Johannesburg, sitting in Palm Ridge, to continue looking for his official police diary and logbook, which the defence team said contained very important evidence.
He could be recalled as a witness at a later stage, Judge Colin Lamont told him.
The trial-within-a-trial was launched following allegations that police and Gininda had been involved in influencing one of Krejcir's co-accused Desai Luphondo into making a confession.
Luphondo's lawyer, Annelene van den Heever, objected to the alleged confession being entered as evidence.
Gininda, who took down the confession, said he had no knowledge of an assault or actions to influence which may have led to Luphondo giving the confession.
Krejcir, Luphondo, Warrant Officers Samuel “Saddam” Maropeng and George Nthoroane, Jan Lefu Mofokeng and Siboniso Miya were on trial for kidnapping, attempted murder and dealing in drugs.
They allegedly recruited a man known as Doctor Nkosi to help smuggle 25kg of tik (methamphetamine) to Australia.
He worked for a cargo company at OR Tambo International Airport, when he disappeared with the shipment.
Krejcir and his co-accused allegedly then kidnapped and tortured his brother, Bheki Lukhele, in a bid to have him reveal his sibling's whereabouts.
Nkosi has also testified in the trial, where he confessed to stealing the drugs.
