Officers took Satoshi Shiroi, 66, and his girlfriend, 46, into custody for the possession of a minuscule amount of stimulant drugs in and around his residence in Edogawa Ward in March. According to police, the drugs were purchased from an organized crime group.
Shiroi, who is currently employed as a taxi driver, has denied the charges of possession but admits to having used drugs between April 1 and 3. His girlfriend has reportedly admitted to the possession charges.
Shiroi joined the force in 1971. He worked primarily as the head of the organized crime division. He resigned from his post in 2009.
During his tenure, he was awarded Superintendent General of the Metropolitan Police commendations on 62 occasions, including 10 times for stimulant drug busts.
