Tokyo police said Tuesday they have obtained arrest warrants for three Romanian men suspected of being connected with a ring that has stolen $45 million from banks with fake cards in more than 20 countries.

The three, all aged 28, allegedly stole ¥11.5 million from an automated teller machine at a convenience store in Tokyo on Feb. 20 using counterfeit cards based on credit card data from an Omani bank, the police said.

The three have already left Japan, and the police have asked immigration authorities to provide information.

It is suspected the three are related to a cybercrime organization whose eight members were indicted by the U.S. Justice Department earlier this year for stealing $45 million from ATMs in more than 20 countries in December 2012 and in February.
