Liam Payne had traces of “pink cocaine” and other drugs in his system when he died after falling from a hotel balcony last week, media reports from Argentina say.
Payne, 31, died after falling from the Casa Sur Hotel’s third floor in Buenos Aires.
Local law enforcement is treating his death as “inconclusive” and seeking the dealer who supplied him with drugs that evening.
Early results from toxicological tests have shown traces of benzodiazepine, crack cocaine, cocaine and “pink cocaine” – a combination of ketamine, methamphetamine and MDMA.
“A second test is to follow to determine the nature of the drug.”
It comes after reports Payne’s funeral could be held next month.
Following the star’s death in Buenos Aires on October 16, Argentinian newspaper Clarin claims his body could remain in Argentina for 10-15 days.
Once toxicological tests have been performed, Payne’s remains will be able to be returned to his family in the UK.
“We are supporting Liam Payne’s family and are in contact with local authorities,” the British Embassy said.
The Strip That Down singer died from “multiple traumas” that caused “internal and external bleeding”.
The singer fell from a third-floor balcony at the Casa Sur Hotel in Buenos Aires, and preliminary autopsy findings reported by the Daily Mirror newspaper found the result was consistent with his 10m fall.
Police found a bottle of whiskey, a lighter and a white powder in the room, and medications that included clonazepam – which is used to treat epilepsy, panic disorders or involuntary muscle spasms – and energy pills.
