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....

Mr. Combs is facing sex-trafficking and racketeering conspiracy charges, which include accusations that he or his associates kidnapped Ms. Clark twice while she worked for him.

Capricorn Clark described a brief car chase that took place the morning Sean Combs allegedly broke into Kid Cudi’s home.
