A former employee of Sean “Diddy” Combs took center stage in his federal criminal trial Thursday and testified that he physically and sexually assaulted her on multiple occasions during the time she worked for him.

Combs tried to control all aspects of Ventura Fine's life during their decade-long relationship, from her music to her social circle and more.

Prosecutors have told jurors the violence was part of an alleged sex trafficking and criminal racketeering enterprise led by Combs that began in 2008, in part to shield him from outside scrutiny.
