Bank of Tokyo-Mitsubishi is preparing to compensate customers whose accounts were compromised by counterfeit cash cards to the tune of about 300 million yen, sources said.

The bank has said it will do so if its own investigators confirm the customers, who were victimized while playing golf, were not responsible for the deposits stolen.

In January, police in Kanagawa, Chiba and Shizuoka prefectures arrested 10 men who allegedly had broken into buildings at golf courses and scanned cash cards taken from lockers while the owners were playing golf.
