Blac Chyna was reportedly in possession of ecstasy pills when she was arrested.
The model was arrested for public intoxication and possession of a controlled substance at the Austin International Airport in Texas on Friday (29.01.16) and officers discovered the drugs when called to the scene after she became abusive to airline staff.
According to a police affidavit obtained by PEOPLE, officers discovered two white pills inside a sunglasses case and after testing they were revealed to be methylenedioxy-methamphetamine, known as ecstasy.
Police said she was "going from extremely angry, cursing at everyone then to crying" during the incident.
After her release, Blac's new boyfriend, reclusive reality TV star Rob Kardashian, drove 1,377 miles from Los Angeles to Austin to pick her up.
Meanwhile, Rob has recently joined Snapchat under the username "Robphuckedme."
He posted a short video featuring a close up of his face and Blac warned other women not to send explicit pictures to her "boo".
Rob's family are said to be furious about the relationship as Blac has been feuding with his sister Kylie Jenner, who is dating Blac's ex fiance Tyga, for some time.
