On January 25, 2006, Ologun allegedly assaulted Katsuyuki Itō, the president of the entertainment agency, R&A Promotions, to which Ologun belongs in Shibuya. Police deliberated whether to send prosecution documents to court in lieu of the charges. According to the investigation, Ologun reportedly seized the president's clothes and acted violently by throwing around furniture because of a dispute over payment. John Muwete Muruaka, who is famous in Japan as the former private secretary of the scandalized Representative Muneo Suzuki and a member of the same agency as Ologun, happened to be there and tried to stop the fight, resulting in a scuffle between the two men.
