The results of a urine test given to Kiyohara, 48, after his initial arrest earlier this month revealed the presence of kakuseizai, or stimulant drugs. The former member of the Yomiuri Giants and Seibu Lions has admitted to injecting and inhaling the drugs.
On February 2, Kiyohara was first arrested for possession of stimulant drugs after a search of his residence in Minato Ward revealed 0.1 grams of the illegal substances.
Last week, police arrested the ex-slugger’s suspected dealer. Kazuyuki Kobayashi was taken into custody over the alleged sale of 0.2 grams of stimulant drugs to Kiyohara for 40,000 yen at a convenience store parking lot in Ota City, Gunma Prefecture.
Over his 22-year career, Kiyohara established himself as one of Nippon Professional Baseball’s greatest sluggers. In his first season with the Lions in 1986, he slugged 31 home runs and was awarded Rookie of the Year honors. He ended his career with 525 home runs, which ranks fifth in NPB history.
