Tokyo police are moving to arrest a former sumo wrestler on suspicion of extorting about 39000 dollars from Ozeki Kotomitsuki. Kotomitsuki told police that he placed bets through a hairdresser who styled traditional topknots for sumo wrestlers. The hairdresser belongs to the Onomatsu stable. Police have learned that last December Kotomitsuki asked an Onomatsu stable wrestler to pay him about 55000 dollars he won betting on baseball. But a brother of the man who owed Kotomitsuki the money, a 38-year-old former wrestler, allegedly demanded hush money implying he had ties to organized crime. The police also suspect the former wrestler, who retired from professional sumo in 1997, later tried to extort more than one million dollars from Kotomitsuki. The police say criminal organizations may be involved in the gambling operations.
