The attackers used virtual telephony with number substitution and called Czech residents, posing as employees of the state banking supervisory authority. During the conversation, they persuaded the victims to provide remote access to their phone or computer or to find out bank card details and transfer funds to controlled accounts. In several cases, the fraudsters convinced their victims to withdraw cash and hand it over to a fake courier who was supposed to deliver it to a safe place.

In this way, they managed to defraud at least sixteen residents of the Czech Republic of over 5.5 million hryvnias. The funds obtained from illegal activities were converted into cryptocurrency or used to purchase luxury cars and real estate, which were registered in the names of friends and relatives.

The police have established the location and identities of the criminals. Law enforcement officers conducted 23 searches, as a result of which, with the force support of KORD fighters, a special police battalion and criminal investigation officers of the Main Department of National Police in Odessa region, they detained all nine participants in the criminal scheme along with the organizer. During the search, computer equipment and mobile phones with evidence of the crimes committed, as well as the suspects' luxury cars and more than one hundred thousand dollars in various currencies were seized.

Investigators of the National Police have charged the Ukrainian defendants with fraud committed on a particularly large scale by a criminal organization. They face up to twelve years in prison with confiscation of property. The foreign criminals were detained on the basis of a prosecutor's order, and petitions have been submitted to the court for referral to the court for their subsequent extradition to the Czech Republic.

The JIT—an agreement to create a joint investigative team, concluded between Ukrainian and Czech law enforcement officers and implemented under the procedural guidance of the Prosecutor General's Office—helped law enforcement officers quickly stop the criminal activities of an international criminal organization.

This is the second case of a successful investigation into illegal call center activities under the agreement to create a joint investigation team (JIT) with Czech law enforcement. In September 2023, the National Police of Ukraine extradited six fraudsters to Czech law enforcement officials, who are currently in custody.
