Spokesperson for the Consular Service Department of the Ministry of Foreign Affairs of Ukraine Vasyl Kyrylych has confirmed the arrest of three Ukrainian citizens on suspicion of involvement in cyber crimes.

"According to the U.S. Justice Department, three Ukrainian citizens were arrested in European countries at the request of U.S. law enforcement agencies, and each of them was accused of committing cyber crimes," Kyrylych told the Kyiv-based Interfax-Ukraine on Thursday.

He said Ukraine's consul had established contact with representatives of law enforcement agencies.

"Information was confirmed about the detention of these citizens of Ukraine, as well as the presence of an American lawyer who defends the rights and legitimate interests of one of the arrested Ukrainians," he said.

An informed source told Interfax-Ukraine that one of the Ukrainians was detained in Germany and had already been sent to U.S. law enforcement agencies.

Regarding the other two, one was detained in Poland and the other in Spain. U.S. law enforcement agencies have requested extradition.

As earlier reported, the U.S. Justice Department on Wednesday, August 1, reported the arrest of three Ukrainian citizens on suspicion of involvement in the hacking group "Fin7."

"Three key members of a complex international hacker group working in Eastern Europe have been detained and are in custody," the Justice Department said in a statement. The names of the suspects are Dmytro Fedorov, Fedor Hladyr and Andriy Kopakov.

The Justice Department said since 2015 more than 100 American companies, including restaurants, gaming and hotel business, have been victims of the Fin7 group, also known as the Karbanak Group and Navigator.

The members of Fin7 hacked thousands of computer systems, stole millions of these bank cards, which were resold to third parties.

"The three Ukrainian nationals indicted today allegedly were part of a prolific hacking group that targeted American companies and citizens by stealing valuable consumer data, including personal credit card information, that they then sold on the Darknet," said Assistant U.S. Attorney General Brian Benczkowski.
