A former LAPD cop claims that Grammy Award-winning artist Sean 'P Diddy' Combs was responsible for hiring a killer to shoot Tupac Shakur in a drive-by in 1996.
Both Diddy, from New York, and Tupac, in Los Angeles, had been caught up in a bitter rivalry between East and West Coast rappers, the Huffington Post reports.
Christopher Wallace, aka Biggie Smalls - a close friend of P Diddy - was shot dead six months later in a revenge killing, according to retired detective Greg Kading, who once led a special task force that investigated the shootings.
Kading claims in a new documentary that Diddy hired Crips gang member Duane Keith 'Keffe D' Davis to kill Shakur and his manager Marion Hugh 'Suge' Knight for $1million.
But on the night of the fatal shooting, on September 7, 1996, it was actually Keffe's nephew Orlando 'Baby Lane' Anderson who shot the 25-year-old rapper dead, according to the ex-cop. Suge escaped unharmed.
The documentary, Murder Rap, features a 2008 interview with Keffe where he claims to have heard Diddy declare in a room full of Crips members that he'd 'give anything for Pac and Suge Knight's heads'.
He goes on to say in the police interview that the rapper had later approached him and offered him $1million to kill the pair.
Former LAPD detective Kading says he was able to 'trap' Keffe into giving him information about Shakur's murder to avoid a harsher sentence for another crime.
Kading says that in retaliation for Tupac's murder, Suge hired rival Blood gang member Wardell 'Poochie' Fouse to kill Diddy's long-time friend Biggie Smalls for just $13,000.
Suge is currently in jail awaiting trial after running over two men outside a Compton, California, burger stand in late January 2015, killing one and seriously injuring the other.
He later turned himself in to police, and his attorneys have contended that he was fleeing armed attackers when he ran over the men.
Court records show a judge has now cut his access to phone calls and non-attorney visitors at the request of a sheriff's detective investigating the case.
Kading claims that the rap mogul was behind the murder of Biggie - also known as The Notorious B.I.G. - who was one of the biggest rappers in the U.S. when he was shot dead on March 9, 1997. He was 24.
The artist was killed while leaving an awards ceremony at Peterson Automotive Museum in Los Angeles.
He got into the back of a GMC Suburban car in a three-vehicle convoy, but before the cars moved, a black Chevy SS Impala pulled up alongside his window and sprayed gunfire.
Kading was assigned to reopen the rappers' murders in 2006 after Biggie's mother Voletta Wallace sued the LAPD over claims they had covered up the real killer in her son's murder - allegedly a rogue cop.
Conspiracy theories abounded after the rappers' deaths.
Many believed the murders were part of a 'war' between top East and West Coast rappers - Diddy and Biggie were part of the East Coast, New York-based, rap scene while Shakur belonged to the West Coast, LA-based scene.
But another popular theory was that Biggie's death may have been the work of David Mack, a corrupt former LA police officer who served 14 years in jail for a $722,000 armed bank robbery in LA in 1997.
