Jury in Sean "Diddy" Combs' federal sex-crimes trial heard testimony from a witness alleging the music mogul dangled her over a 17-story balcony and a forensic video expert who showed the much-discussed 2016 hotel footage of Combs attacking Cassie Ventura Fine.

Bryanna "Bana" Bongolan, a designer and friend of Ventura Fine, alleged on June 4 that she "was held over a 17-story balcony" by Combs in September 2016. She testified that the rapper threw her on balcony furniture, and she was left with a bruise on the back of her leg, as well as neck and back pain.

"I'm the devil, and I could kill you," Combs allegedly told Bongolan on a different occasion.

Frank Piazza, a forensic video expert, walked the jury through a compilation video that he made, which showed the much-discussed 2016 hotel footage of Combs attacking Ventura Fine.
