A second woman testified on Thursday that Sean “Diddy” Combs sexually assaulted her as part of what federal prosecutors allege was a sex-trafficking and racketeering scheme masterminded by the hip-hop mogul.

The woman, testifying under the pseudonym Mia, told a jury in Manhattan federal court that she worked for Combs as a personal assistant and director of development and acquisition from 2009 to 2017, starting when she was about 25 years old.

“He’s thrown things at me, he’s thrown me against the wall, he’s thrown me into a pool, he’s thrown an ice bucket on my head, he’s slammed my arm into a door, and he’s sexually assaulted me,” Mia said.

Combs, 55, has pleaded not guilty to five counts including racketeering and sex trafficking. He faces up to life in prison if convicted on all counts.

Mia said that Combs’s conduct towards her was “the most shameful thing of my life” when challenged by his defense about why she hadn’t reported him, adding that having to talk about it now was a traumatic experience but that being scared into silence would not help others.

Sometimes he treated her like a best friend, sometimes he was terrifying and humiliated her in front of others, making her feel like “a worthless piece of crap”, she told the jury in New York.

She also described feeling trapped in the situation, finding that in previous interactions with police the officers were simply awed to be dealing with the famous artist Diddy, and also being terrified of him.

“I didn’t want to die or get hurt,” she said. She had assumed she would take her secret to her grave, but now had felt able to take the stand.

“I couldn’t tell him ‘no’, like, about a sandwich. I couldn’t tell him ‘no’ about anything. There’s no way I could tell him ‘no’,” Mia said, adding that if she had left or been fired she feared that Combs would “ruin my future”.

Testimony in the closely watched trial in Manhattan federal court is in its third week. Prosecutors say Combs, the founder of Bad Boy Records, coerced women over two decades to take part in days-long, drug-fueled sexual performances with male sex workers known as “freak offs”.

Mia’s testimony was not about sex parties but about allegedly being raped in private, at his home when she was assisting him, such as in packing for a trip. He made her feel “like trash”, she said.

Mia told jurors Combs climbed on top of her while she was sleeping and raped her while she lay frozen with fear. In another incident, she testified that Combs grabbed her head and put his penis in her mouth, while she did not fight back. As she testified on Thursday, she fought back tears and often looked down at her lap.

Combs’s lawyers have acknowledged he was at times abusive in domestic relationships but said any sex was consensual.

They have also said that women who participated in sex party marathons, dubbed by Combs as “freak offs”, did so consensually.

Over four days of emotional testimony during the first week of trial, Combs’s ex-girlfriend Casandra Ventura told jurors Combs physically and emotionally abused her throughout their tumultuous 11-year relationship.

Ventura, a rhythm-and-blues singer known as Cassie, said she participated in the “freak offs” because she feared Combs would release sex tapes of her if she didn’t, but also because she loved him.

Friends and associates of Combs and Ventura have also testified about Combs’s alleged abuse, describing Combs as a domineering figure who relied on bodyguards and associates to enable his alleged crimes and keep victims in line.

Dawn Richard, a former member of the pop group Danity Kane, testified last week that she felt threatened when Combs told her to keep quiet about what she saw.

Richard faced a sharp cross-examination by one of Combs’s lawyers, who sought to point to inconsistencies between her testimony and what she said during interviews with prosecutors.

Last week, Scott Mescudi – the rapper known as Kid Cudi – testified that his car was set on fire in 2012, shortly after Combs learned that Mescudi had a romantic relationship with Ventura.

Prosecutors say the alleged arson of Mescudi’s car was one of several violent or illegal acts that Combs or his associates undertook to prevent women from leaving his orbit and keep his abuse quiet.

The trial has drawn intense media coverage due to Combs’s cultural influence and role in taking hip-hop mainstream through legendary artists like the Notorious BIG.

Combs was arrested in Manhattan last September and is being held at a federal prison in Brooklyn when not in court.

The trial will resume on Friday and is expected to last several more weeks.
