The appointment was made by acting Police Commissioner Andrej Jurič as he decided against picking any of the candidates that applied for the call for applications to fill the post of NBI director.

An announcement on the web site of the Slovenian police said that upon the handover, Jurič thanked Lamberger for his correct cooperation and wished the new acting director to successfully head what he described as a very demanding filed of police work.

According to the release, Lepoša has been with the police force for 28 years. Between 2008 and 2015 he headed the property crime section at the criminal police division of the Ljubljana Police Department and after that the homicide and sexual offences section at the same division.

Last year he moved to the development and system task division in the service attached to the police commissioner.

Out of the three candidates who applied for the call for the NBI director, one has withdrawn his bid, while the other two have been cleared as suitable by a special vetting commission.

Media reported that the trio applying for the job were Igor Lamberger, Boštjan Lindav, who until recently headed the criminal police directorate, and Edvard Ermenc, a senior judge at the Celje Administrative Court, who later withdrew.

The media initially tipped Lamberger as the favourite for the job, but later alleged that he had lost support by defending police officers in the face of allegations by Interior Minister Aleš Hojs that police actions were politically-motivated, which was in reference to raids at Economy Minister Zdravko Počivalšek as part of the probe in the procurements of medical equipment.

Lamberger took over as acting NBI director on 6 May to replace Darko Muženič, who was dismissed by the then Police Commissioner Anton Travner, who has since resigned. Muženič is challenging his dismissal in court.
