Promoter John Callaghan had denied working for the six-times World Championship runner-up, claiming he was only a friend and fan. 35 bets were placed on White's matches over the past year with most of the bets being placed on frames predicting the scores from matches.
A statement from the game's governing body the World Professional Billiards and Snooker Association said: "Following statements made in the Daily Star on Sunday 17th June 2012 regarding the betting activity of an alleged aid to Jimmy White, the WPBSA has taken the decision not to conduct a full investigation having found no evidence of any breach of the rules.
The WPBSA process of making enquiries is very thorough and has involved liaising with the Gambling Commission Sports Betting Intelligence Unit and the betting industry. The WPBSA have not found any evidence of inappropriate betting activity in relation to the statements in this article or by Jimmy White and therefore no further action will be taken.
