Over the weekend, YouTube star Jake Paul threw a party at his Calabasas mansion that resulted in a woman’s claim that she had been drugged through spiked drinks.

The drugging allegation came as one concerned mom took to Facebook’s group “Moms of Conejo Valley” Sunday night claiming that her underage daughter and a group of friends had something slipped in their drinks. Her daughter, as well as eight other girls, ended up at West Hills hospital incoherent, half naked and unable to walk or talk.

The 22-year-old was throwing a party for rapper Desiigner that evening and the LAFD confirmed that they spent Saturday night transporting two patients for intoxication from the mansion.

While it’s not clear if the mother of the alleged victim was the one who filed a report, a lieutenant with the Lost Hills Sheriff’s Station said detectives have not yet been able to verify the validity of the Facebook post. In response to the accusation, Jake’s attorney, Larry Stein reported “We take this claim very seriously, and are working with authorities to make absolutely sure we do our part to uncover the truth.”

The investigation is in its early stages, and law enforcement is asking anyone with information to reach out to the L.A. County Sheriff’s Department.
