NEW YORK (AP) — A former top aide to Sean “Diddy” Combs testified Tuesday that the hip-hop mogul threatened to kill her on her first day on the job and kidnapped her at gunpoint as he sought to kill rapper Kid Cudi.

Capricorn Clark’s account of Combs’ volatile, violent tendencies launched the third week of testimony at his sex trafficking trial in federal court in Manhattan.

Prosecutors called Clark, the former global brand director for Combs’ Bad Boy Entertainment, as they work to prove he led a racketeering conspiracy spanning two decades that relied on beefy bodyguards, death threats and a code of silence among frightened staff to ensure he got what he wanted.

Combs, 55, has pleaded not guilty to multiple counts of an indictment accusing him of a pattern of abuse toward his longtime girlfriend Cassie, whose legal name is Casandra Ventura, and others. If convicted he could face 15 years to life in prison.

Clark’s testimony came days after Kid Cudi, whose legal name is Scott Mescudi, testified that Clark called him from a car outside his home in December 2011 and told him that Combs, angered because Cudi was dating the singer Cassie, had kidnapped her and forced her to ride him with him to Cudi’s home.
