A former wrestler in his 50s who once worked as an attendant in sumo's top division said he was approached by an attendant of another grappler to take part in match-fixing some 30 years ago.

According to the man, who requested anonymity, the attendant for another makuuchi-division wrestler approached him with an offer to throw their match.

His wrestler needed just one more win to claim a Fighting Spirit Prize, and the other attendant approached him about the scheme in the dressing room before the bout.
