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.

The 55-year-old hip-hop mogul has been charged with sex trafficking, racketeering conspiracy and transportation to engage in prostitution.

Testimony Wednesday in the sex-trafficking and racketeering trial of Sean "Diddy" Combs was marked by a surprise motion for a mistrial from Combs' defense team. The play, prompted by a reference to destroyed evidence in an arson investigation, was quickly turned back by the judge, who has kept a tight grip on the headline-grabbing trial.
