He is the fourth MMC official to be held in the scandal. The automaker's soccer team, the Urawa Red Diamonds, is a professional J. League soccer club also headed by Shimizu.Police are investigating the cash transfers, which involve several banks and manufacturers over several years, to see whether the payoffs are illegal under Japan's Commercial Code, police sources said.
