TOKYO: Former Japanese baseball star Kazuhiro Kiyohara has been arrested on suspicion of possessing stimulant drugs, Tokyo police said on Wednesday, in a humiliating fall from grace for the one-time sporting idol. The 48-year-old former Yomiuri Giants slugger, once one of the biggest names in Japanese baseball, was taken into custody and accused of possession of approximately 0.1 gram of an undisclosed substance after police raided his home in the plush Azabu district of Tokyo on Tuesday night. Kiyohara admitted the drugs belonged to him and did not resist arrest, the Tokyo Metropolitan Police Department told AFP. He is set to undergo medical examinations to determine whether he was using the stimulants himself, it added.
