A massive party at a Calabasas mansion hosted by YouTube personality Jake Paul is being investigated by the Los Angeles County Sheriff’s Department.

Paul posted a video prior to a party at the mansion in Calabasas on Saturday, May 4. The event was a celebration for a rapper who goes by Desiigner, TMZ reported.

Clips posted on social media show the party was packed with guests.

Afterward, one woman filed a report with the Malibu/Lost Hills sheriff’s station that her drink had been spiked, according to sheriff’s Lt. Kim Mendoza.

And a Los Angeles County Fire Department official confirmed two intoxicated patients were transported to a hospital from the 23500 block of Park South Street – one at 11:30 p.m. Saturday and another at 1:06 a.m. Sunday.

On Sunday, a member of the “Moms of Conejo Valley” Facebook page wrote that her daughter was one of several attendees who had been drugged and ended up in a hospital, incoherent, half naked, and unable to walk or talk.

It’s not clear if the woman who posted that message on Facebook is the mother of the woman who filed a report with the Sheriff’s Department. The poster did not respond to an inquiry from KTLA, and investigators have not been able to confirm the validity of the post, Mendoza said.

In a statement from a deputy spokeswoman, the Malibu/Lost Hills sheriff’s station said it was “made aware of a possible single occurrence of unwillful impairment.”

“Detectives are in the beginning stages of information gathering for the incident. The Sheriff’s Department treats allegations such as these seriously, and will use all known resources to investigate,” the statement continued.

No other details were available.

Anyone with information is asked to please call the Malibu/Lost Hills sheriff’s station at 818-878-1808, or CrimeStoppers at 800-222-TIPS.
