Lawyers for Sean "Diddy" Combs have hit out at a new Netflix documentary produced by rapper 50 Cent, which they say is "a shameful hit piece" that "relied on stolen footage".

The four-part documentary, titled Sean Combs: The Reckoning, was released on Tuesday and is billed as a "staggering examination" of the hip-hop mogul, who was convicted on prostitution-related charges earlier this year.

It includes what Netflix described as "explosive" footage of Combs filmed in the days before his arrest, including a phone conversation with his lawyers.

The director said she obtained the footage legally, but Combs' spokesman said it was "fundamentally unfair, and illegal" to use his private footage.

He also said it was "staggering" that Netflix had given creative control to 50 Cent, who he described as "a longtime adversary with a personal vendetta".
