Johannesburg - Five laptops possibly containing sensitive information, including data on investigations into Radovan Krejcir, have been stolen from Interpol's Pretoria offices, The Sowetan reported on Wednesday.
Investigators indicated one of the laptops stolen belonged to an officer who was involved in George Louca's extradition to South Africa from Cyprus, the newspaper reported.
Other possible information on the laptops included secret witness lists and information linked to investigations into international crime syndicates.
The burglary happened over the weekend, with Interpol using offices seconded to them by police.
The thefts first took place on Saturday, with burglars returning again on Sunday.
It was believed the thieves had access cards and key codes to gain entry into the offices and building. The offices were being used by three colonels and two captains.
Lt-Gen Solomon Makgale confirmed to the newspaper the thefts had taken place, but would not confirm sensitive information had been compromised.
“We don't want to get ahead of ourselves. We are busy with investigations,” he said.
No arrests had been made.
Krejcir and five others are on trial facing charges of kidnapping, attempted murder, and dealing in drugs.
Louca, a Cypriot national, is accused of killing Teazers strip club boss Lolly Jackson. - Sapa
