In 1994, he was involved with John Daly for the High Noon in Hong Kong boxing event. The fights were called off at the last minute when Barry Hearn scuttled the bout by withdrawing his fighters, when no purses were forthcoming from Top Rank. In 2000, citing extortion; Arum voluntarily testified to having paid IBF president Robert W. "Bobby" Lee, Sr. $100,000 in two installments in 1995, as the first half of a $200,000 bribe, through "middleman, Stanley Hoffman", adding that Lee had first demanded $500,000 to approve the Schulz–Foreman fight, but had settled for the lesser amount of $200,000 (half of which was never paid). Lee was indicted for racketeering in 1999, but convicted of money laundering and tax evasion in 2000. Following his testimony, Arum was sanctioned and fined $125,000 by the Nevada State Athletic Commission. Boxing promoters Cedric Kushner and Dino Duva also admitted to making similar payments to Lee. Oscar De La Hoya successfully sued Arum and was legally released from his contract with Top Rank in January 2001. Following years of acrimony; he and De La Hoya publicly salvaged their relationship. In 2003, Arum complained about the judging in the September 13 bout between Oscar De La Hoya and Sugar Shane Mosley and suggested there was a vendetta against him from a member of the Nevada State Commission that led to De La Hoya's loss. Arum later made an apology for the remark which commission chairman Luther Mack accepted. In the first week of January 2004, FBI agents raided Arum's Top Rank office in Las Vegas. Arum was on vacation when his office was raided, and the FBI originally declined to comment on the raid. The media reported that the FBI was investigating allegations that Top Rank was involved in fixing the rematch between De La Hoya and Shane Mosley, even though De La Hoya lost and Arum was De La Hoya's promoter. The federal agency also announced that it was investigating some of Eric Esch's fights, as well as the Jorge Páez–Verdell Smith fight. The investigation closed in the summer of 2006 with no charges being filed. In 2007, "Yahoo Sports" reported that, "Floyd Mayweather Jr. essentially accused Arum, who promoted him from the beginning of his career in 1996 until 2006, of underpaying him, exploiting his talents and manipulating officials." Mayweather, who also became a boxing promoter, stated to "Yahoo Sports" in 2015, "I don't have anything bad to say about Bob Arum."
