Bence Rétvári, the parliamentary state secretary of the interior ministry, said Hungarian police have been cracking down on Ukrainian criminal groups that have committed various types of online fraud.
Rétvári said in a post on Facebook that the scams included cryptocurrency fraud and fake package deliveries.
Police have identified 169 Ukrainian suspects, including managers and front men for the criminal gang's money laundering activities.
International arrest warrants have been issued against people involved in money laundering, phishing and operating fake call centres.
Retvari listed various crimes committed throughout Hungary, and noted that the largest ever illegal call centre network also operated in Ukraine in which Hungarians were swindled out of money by criminals pretending to call from banks.
