Family members of Cassie Ventura and Sean ‘Diddy’ Combs have been in court this week during graphic testimony in his federal sex-trafficking trial.

Casandra Ventura said the mogul pleaded with her in text messages and followed her to her apartment after striking and dragging her in the hallway of a Los Angeles hotel.

Ms. Ventura said she wore a masquerade-style mask and provocative clothing from a “sex store,” and that she and the man took Ecstasy and drank alcohol before they had sex and Mr. Combs watched.
