The Los Angeles County Sheriff's Department is investigating a complaint from a woman who said she suspected that she was drugged after she "blacked out" at a party hosted by YouTuber Jake Paul on Saturday night, a police official told BuzzFeed News.

A spokesperson for the Lost Hills/Malibu Station said police received the report from the woman Sunday night, a day after Paul threw a birthday party for the rapper Desiigner at Paul's Calabasas mansion.

The woman told police that she may have blacked out after "something was put in her drink," Sgt. Foss, who didn't provide his first name, told BuzzFeed News on Monday.

A spokesperson for the Los Angeles County Sheriff's Department confirmed that detectives were looking into "a possible single occurrence of unwillful impairment" related to the party.

"On Sunday, May 5, 2019, the Malibu Lost Hills Sheriff’s Station was made aware of a possible single occurrence of unwillful impairment related to a party attended on May 4, 2019," the spokesperson said in a statement. "Detectives are in the beginning stages of information gathering for the incident.
