Jennifer Beidel, a former US attorney for the Southern District of New York, tells the BBC that because of the length of Casandra Ventura and Sean "Diddy" Combs' relationship - about a decade, on and off - Ventura's testimony in this case is crucial.

On the stand in court Tuesday, Cassie alleged Combs would "bash my head, knock me over, drag me, kick me, stomp me in the head if I was down."

Cassie Ventura, a longtime girlfriend of Sean "Diddy" Combs, said she loved the hip-hop mogul and felt a sense of duty to join "freak offs."
