Liam Payne had 'pink cocaine' in his system at the time of his death – report

Former One Direction singer Liam Payne had multiple drugs in his system, including crack cocaine and methamphetamine, when he fell to his death from a hotel balcony in Argentina, according to anonymous Argentine sources familiar with the preliminary toxicology report.

The British singer and former One Direction member died last week aged 31 after falling from a third-floor hotel room in Buenos Aires.

ABC News and TMZ reported that a cocktail of drugs called “pink cocaine” — containing methamphetamine, ketamine and MDMA — was found during a partial autopsy, along with crack cocaine and benzodiazepines. Both outlets cited anonymous sources familiar with the preliminary tests.

The Associated Press reported that an unnamed official said preliminary toxicology reports suggested evidence of cocaine exposure, but stressed that those preliminary results did not offer an accurate reading of how much was circulating in his blood at the time of his death.

Final toxicology results are not expected to be released for several weeks.

The Associated Press reported that the official spoke on condition of anonymity because he was not authorized to brief reporters. The initial report was widely reported in local media on Monday.

Argentina's public prosecution is investigating the case, which is not unusual in sudden or unexpected deaths.

Payne's autopsy concluded that her cause of death was consistent with blunt force injuries sustained when she fell three stories from the hotel window. Prosecutors have denied anyone else was involved.

Argentinian investigators found 31-year-old Payne's hotel room with what appeared to be broken furniture and narcotics and alcohol spilled on it, leading public prosecutions to speculate that Payne suffered a substance abuse-induced breakdown during his fall. The prosecution said Payne may have fallen from the balcony of his hotel room in a “semi- or fully unconscious” state.

Photos from inside Penn's hotel room released by local media showed snow-like powder on a table and a broken TV screen. Police also discovered a blister pack of clonazepam, a central nervous system depressant, and over-the-counter medication scattered among Paine's belongings. Shortly before Payne's death, the hotel manager called 911 to report a guest acting aggressively and under the influence of drugs and alcohol.

Investigators are trying to find out who sold the drugs Paine took at the Casasur Hotel in the Argentine capital, Palermo. Police have taken statements from at least three hotel employees, as well as two women who visited Penn's hotel room in the hours before his death.

Fans and pop industry majors around the world responded with expressions of grief.

The late singer's father, Geoff Payne, was in Buenos Aires on Monday meeting with prosecutors and other local officials in an effort to organize the repatriation of the body.

Argentine authorities hope to release the body next week, clearing the way for Geoff Penn to fly home and hold a funeral in England, where hundreds of fervent One Direction fans gathered on Sunday to mourn the singer.
