An international law enforcement operation involving Montenegrin authorities and the Interpol resulted in Ziemian getting found hiding under a false identity in a newly developed residential area in Podgorica.
After conducting searches, officers of the Sector for Fighting Crime - Group for High-Tech Crime and the Regional Security Center "Centar" confiscated technical devices and items suspected of being the result of a criminal act, according to Radio Slobodna Evropa.
According to the police, Ziemian is suspected of money laundering, theft and violation of law, economic crime.
FutureNet's other partner, Stefan Morgenstern, "was arrested in Greece and then in Albania," in 2023 a report said citing the police.
Ziemian will be brought before an investigating judge of the High Court in Podgorica to determine where he would be extradited.
