Death Row Records chief Marion "Suge" Knight is the focus of police and probation officials' investigation into the melee at the Nov. 16 Vibe Awards show, the Los Angeles Times reports.
"Mr. Knight has some special conditions attached to his parole, and we are working with the Santa Monica police to evaluate all the circumstances that took place that evening," Alfred Martinez, Los Angeles regional parole administrator for the Corrections Department, tells the newspaper.
Knight's parole conditions, related to his 2001 release from prison after serving time for assault and weapons violations, prevent him from having contact with his former Death Row colleague Dr. Dre.
Authorities are attempting to determine if the rap producer played a role in the skirmish, for which Knight (who reportedly arrived at the event without an invitation) has denied any involvement. The incident broke out after a man struck Dr. Dre twice, allegedly instigating a brawl in which the attacker was stabbed and seriously injured.
Dre (real name: Andre Young) met with authorities Monday at the Santa Monica, Calif., police station and demanded that his attacker, Jimmy "James" Johnson, be charged with assault and battery, the Associated Press reports, adding that the videotape in question shows Johnson punching Dre at the awards show.
Johnson was then stabbed, allegedly by the rapper Young Buck (real name: David Darnell Brown), described as a protege of Dr. Dre. Young Buck surrendered on Nov. 19 to authorities and is slated to be arraigned Dec. 20.
Knight and Dre co-founded Death Row Records in the early 1990s but had a falling out a few years later.
Attorney Milton Grimes, who once represented Knight and now represents Johnson, denied any involvement by Knight. "As far as I know, my client has no ties whatsoever to Suge Knight," Grimes told the Times.
