Several people were detained on Thursday during an operation codenamed "Purgatory", with the National Crime Agency (NAKA) charging them with several crimes, TASR learnt from Special Prosecutor's Office spokeswoman Jana Tokolyova. "The charges pressed by a NAKA investigator concerned several crimes, such as setting up and supporting an organised criminal group, various corruption crimes, and the misuse of powers. We can't provide any more details given the ongoing investigation," said the spokeswoman. NAKA has been carrying out a raid on the house of former Police Corps president Tibor Gaspar in Nitra since Thursday morning. According to TASR's information, NAKA has been also raiding the homes of other former senior police officers, namely former NAKA head Peter Hrasko and former head of NAKA's financial unit Bernard Slobodnik.
