I was sexually assaulted at Diddy party allegedly attended by Beyoncé, Jay-Z and Lebron James

A man accusing Sean “Diddy” Combs of sexual assault claims in a new lawsuit that he was paraded around the mogul’s home while being made to wear a penis mask and encountered Beyoncé, Jay-Z, LeBron James and other celebrity attendees at a party.

The accuser, Joseph Manzaro, alleges that he was drugged and taken to a home on Star Island, in Miami, owned by Gloria and Emilio Estefan, for Christian “King” Combs’ birthday in April 2015. Once there, he claims Gloria saw him in a “deteriorating state” and told someone to call an ambulance, before Emilio allegedly ushered her away, according to the complaint obtained by PEOPLE.

Manzaro says he then briefly saw James walking in a hallway, who remarked, “Y’all better do something about that,” the complaint states.

The complaint alleges that Manzaro was then taken via an underground tunnel to Combs’ mansion by former porn star Adria English, who is also named a defendant in the suit.

Manzaro then alleges in the complaint that he regained partial consciousness and found him in a room with Jay-Z and Beyoncé, the latter of whom expressed confusion and asked why a “half-naked” man with a sex toy strapped to his face was standing in front of her.

One of the other defendants named in the suit allegedly responded that it was a “punishment,” and that “Diddy wants him to see what we do to snitches.”

The suit alleges that Combs later specifically ordered that Manzaro be degraded in front of others at the party before the plaintiff was stripped and then dressed in a thong and “a black leather mask with a rubber dam forcibly inserted and zipped closed over his head.”

“A locking sex device was affixed to the mask, which protruded from his mouth,” the suit alleges. “Plaintiff was then subjected to degrading and non-consensual acts.”

Manzaro claims he later came across Jacob Arabo, a well-known jeweler, and expressed confusion before Emilio Estefan allegedly instructed the men escorting Manzaro to move him away from Arabo.

The suit further claims that Gloria Estefan again requested an ambulance but was again silenced by Emilio.

The suit described the event as a “freak-off.”

In a statement to PEOPLE, Combs’ legal team strongly denied the allegations levied by Manzaroo.
