Rapper Scott "Kid Cudi" Mescudi took the stand on Thursday to testify as a prosecution witness at hip-hop mogul Sean "Diddy" Combs' sex trafficking trial.

A close look at the case against hip hop mogul Sean “Diddy” Combs, for sex trafficking and racketeering conspiracy, underway in a Manhattan court.

Cassie Ventura and Sean "Diddy" Combs' former assistant testified that he tried to confront Marion "Suge" Knight at a diner. The pair have been rivals since the '90s.

A handful of witnesses took the stand in Sean Combs' sex-crimes trial, including a psychologist, a federal agent and a former aide.

Prosecutors showed the jury photos taken during the raid on Sean “Diddy” Combs’ Miami home last year as a Department of Homeland Security agent took the witness stand.

Homeland Security agent detailed seizing pallets of baby oil from Diddy's Miami home, ex-assistant described Diddy's drug use.

Regina Ventura, the mother of Combs' ex-girlfriend Cassie Ventura Fine, told the court on May 20 she was "physically sick" over the rapper's alleged abuse and said she was once pressured to send him $20,000 after he raged at her daughter. "I was scared for my daughter’s safety," Ventura told jurors.
