DIDDY is “high on the list” of potential suspects involved in the murder of Tupac Shakur, according to the rap legend’s brother.

Mopreme Shakur spoke on Piers Morgan Uncensored about the fatal drive-by shooting in 1996 and how his brother’s mysterious death deserves a fresh criminal probe.

Mopreme discussed theories around how Sean ‘Diddy’ Combs allegedly played a part in the hit after the rap mogul was named over 70 times in the latest legal documents around Tupac’s murder.

Diddy, 54, has always refuted claims he had any involvement in Tupac’s death.

But Mopreme told Piers Morgan he has “doubts” over Diddy’s staunch denial.

And believes ending his brother’s life “involved multiple people, planning, coordination”.

With Diddy being one of those who may have been behind it, the brother says.

Over a decade after Tupac’s death Mopreme revealed the man formerly known as “Puff Daddy” called him to profess his innocence.

Recalling the 2008 conversation Mopreme explained: “He’s basically said he ain’t had nothing to do with my brother’s murder.

“I told him, ‘The truth is still yet to come out, so we gonna see’.

“Here we are 27 – 28 years later and there looks like there is some doubt in that statement.”

When asked about Diddy’s alleged involvement and the call in more detail Mopreme doubled down on his suspicions saying he wasn’t convinced with the rapper’s complete denial.

He said: “I have my doubts.

“I don’t believe it was 100% honest statement – so again, we have to find out what is true and what’s false, what’s real and what’s fake.”

Piers replied: “You think he was lying?”

As Mopreme responded: “Quite possibly and it’s kinda looking that way, in my opinion.

“The theory involving him [Diddy] is quite high on the list”.

Mopreme added that he doesn’t believe Diddy definitely played a part in the assassination but that it is a theory that needs to be looked into thoroughly.

“We gonna see. Just like I told him. I’m not saying nothing until this investigation is over. And then we will see what it is,” he said.

“Everybody knows the suspicions, everybody knows the theories, especially now, [people] are thinking it might be possible, we gonna see.”

Combs has been accused by the man currently being prosecuted for the murder – gangster Duane “Keefe D” Davis – of paying $1 million for Tupac’s assassination, according to the latest court papers obtained by The U.S. Sun.

The jailed music kingpin has been linked to the death for decades due to what prosecutors call a “deadly rivalry” between Combs’ Bad Boy Records and Marion “Suge” Knight’s Death Row Records.

Combs headed up the East Coast with rap sensation Biggie as his main artist whereas Suge dominated the West Coast with Tupac.

Suspect Keefe D has also boasted about Diddy allegedly offering him a $1 million reward for the rapper’s assassination in a chilling secret police interview.

Keefe, 61, appears to be laughing and joking with police about Diddy orchestrating Tupac’s killing in September 1996 in Las Vegas.

Disturbingly in the tape Keefe – and without any firm evidence – alleges that he oversaw the fatal shooting on the request of Diddy.

Court documents also allege that after the shooting, Keefe flew to New York with a Los Angeles police task force to pose undercover to try to gather incriminating evidence.

The focus of the operations was to seek information from Combs and another gangster Eric “Zip” Martin over the murder.
