Toxicology test results indicate Liam Payne had multiple drugs in his system at the time of his death last week, including “pink cocaine”, as well as cocaine, benzodiazepine and crack, ABC News reported citing sources.

Pink cocaine is a recreational drug that includes ketamine, methamphetamine, MDMA, opioids, and/or new psychoactive substances, according to the National Institutes of Health.

A partial autopsy report last week determined that the former One Direction singer died of “multiple trauma” and “internal and external hemorrhage,” as the result of the fall from the balcony of his third-floor hotel room in the Palermo neighborhood of Buenos Aires where he was staying, the local Public Prosecutor’s Office revealed.

Payne’s body will remain in Argentina until the autopsy is complete, according to ABC News, citing sources.

The 31-year-old Payne died at 5:07 p.m. on Wednesday, October 16, after falling from the Casa Sur Hotel balcony and his body was taken to the city’s judicial morgue, where, that night, forensic medical professionals performed the autopsy, the prosecutor’s office said.

As reported earlier, hotel staff raised the alarm about Payne‘s apparently erratic behavior moments before his death, 911 calls have revealed.

A receptionist at the CasaSur Palermo hotel in Buenos Aires, Argentina, notified police that Payne’s life was in danger, according to a recording of two emergency calls.

The hotel staffer alleged that Payne was intoxicated on drugs and alcohol, and had been trashing his room at the time of the disturbance. They called for urgent assistance.

Payne rose to fame as part of One Direction, the pop group formed by Simon Cowell on The X-Factor UK Season 7 in 2010 that also featured Harry Styles, Niall Horan, Louis Tomlinson and Zayn Malik. The group released five studio albums from 2011-15, all of which went platinum in the U.S. and hit No. 1 or No. 2 stateside and in the and UK and were Top 10 around the world.

The group scored four No. 1 singles in Great Britain: debut “What Makes You Beautiful,” “Little Things,” “One Way or Another (Teenage Kicks)” — whose video Payne directed — and “Drag Me Down.” Five others reached No. 2 in the country as One Direction became one of the top-selling boy bands ever.
