Police served fresh warrants Tuesday on two men under arrest who are suspected of installing skimming devices and spy cameras at seven unmanned bank outlets in Aichi and Gifu prefectures and stealing more than 11 million yen from eight customer accounts.

The fresh warrants allege that Mitsuhide Kimura, 37, a resident of Nagoya who has South Korean nationality, and Kenji Tomizawa, 39, a resident of Kuwana, Mie Prefecture, used a counterfeit bank card and stole 168,000 yen from a customer's account at a bank outlet in Nagoya last March 10.

Kimura and Tomizawa have told investigators they installed either skimming devices or spy cameras at the seven automatic teller machine outlets in Aichi and Gifu prefectures of the former UFJ Bank, Hekikai Shinkin Bank and Juroku Bank.

UFJ Bank merged with Bank of Tokyo-Mitsubishi to become Bank of Tokyo-Mitsubishi UFJ in January. Juroku Bank is a regional bank based in Gifu, while Hekikai Shinkin Bank is a credit association based in Anjo, Aichi Prefecture.

The suspects regularly collected the skimming devices to acquire information and got the PIN numbers with the spy cameras, police said.

Last August, the pair stole about 10 million yen at a UFJ Bank outlet in Handa, Aichi Prefecture, police alleged.

They arrested Kimura and Tomizawa in February for allegedly trespassing at a bank outlet in the city of Kakamihara, Gifu Prefecture, so they could measure the height of the ceiling and the size of the ATMs.
