Sean “Diddy” Combs is accused of mistreating Kim Porter, his former partner and the mother of three of his children, in a new docuseries that also details the sexual misconduct allegations the mogul is facing…

The claim is made by Danyel Smith, the former editor-in-chief of Vibe, who is one of many people interviewed in the upcoming docuseries The Fall of Diddy, airing Monday, Jan. 27, and Tuesday, Jan. 28, from 9 to 11 p.m. ET on Investigation Discovery and streaming on Max.

“I’ve seen [Combs] act around Kim in many ways that were just awful and very mean,” Smith alleges in an exclusive clip from the docuseries.

Smith recalls one incident in which she claims she was at a nightclub with Porter and other women when Combs showed up.

He just started hollering at her that she should be at home, not out,” Smith says. “Then he grabbed her handbag and literally turned it upside down. He just emptied it out in front of everybody.”

Kim Porter and Diddy had three children together: Christian Combs and twins Jessie James Combs and D’Lila Combs. Quincy Brown was Porter’s son with R&B singer Al B. Sure! Quincy was adopted by Diddy around 3 years old.

In a statement to PEOPLE regarding Smith’s allegation, Combs’ attorneys wrote: “These documentaries are rushing to cash in on the media circus surrounding Mr. Combs. The producers failed to provide sufficient time or details for his representatives to address unsubstantiated claims, many from unidentified participants whose allegations lack context. By withholding this information, they made it impossible for Mr. Combs to present facts to counter these fabricated accusations. This production is clearly intended to present a one-sided and prejudicial narrative. As we’ve said before, Mr. Combs cannot respond to every publicity stunt or facially ridiculous claim. He has full confidence in the facts and the judicial process, where the truth will prevail: the accusations against him are pure fiction.”

Combs is currently in jail as he awaits trial on federal charges of sex trafficking, racketeering and transportation to engage in prostitution, following a September indictment. He has pleaded not guilty.

The Fall of Diddy also features interviews with D. Woods, a member of Danity Kane, the girl group formed on Combs’ former reality show Making the Band, and several former of Combs’ employees and accusers.

The Fall of Diddy airs Monday, Jan. 27, and Tuesday, Jan. 28, from 9 to 11 p.m. ET on Investigation Discovery and streams on Max.
