Knight entered the awards show without an invitation and sat just a few feet behind Drew, who was receiving a lifetime achievement award.
Attorney Milton Grimes, who once represented Knight and now represents Johnson, denied any involvement by Knight.
"As far as I know, my client has not ties whatsoever to Suge Knight," Crimes told the Los Angeles Times.
The Times, citing unidentified sources, said Santa Monica police and agents from the state Department of Corrections have been interviewing witnesses and reviewing video footage to examine Knight's actions before, during and after the melee.
