Argentinian journalist Paula Varela claims Liam Payne fainted on the balcony in Buenos Aires as the investigation into the death of the singing star, 31, continue

The horror moment Liam Payne plunged from his third-floor Buenos Aires hotel balcony was captured on CCTV, an Argentinian broadcast journalist has claimed.

Paula Varela said the footage showed the former One Direction singer had fallen after he fainted on the balcony but alleges authorities were keeping it secret. Liam died earlier this month after the singing star tragically fell to his death to the shock of the world.

The 45-year-old also claimed on a popular Argentinian TV show that a night worker at the CasaSur Palermo Hotel who had struck up a close relationship with Liam was the focus of an ongoing investigation which was trying to establish who supplied him with the drugs suspected of contributing to his death on October 16.

Paula said on Socios del Espectaculo, a show broadcast on Buenos Aires-based TV station Canal 13: There is footage that is not being released to the media with the balcony scene where you see that Liam faints and tragically because of where he is, falls from that balcony. If he had been beside his bed he would have fallen on his bed.

Its not that he jumped deliberately. This footage is in the official case files. She also said: Theres a lad whos being investigated, he was working nights at the hotel. He struck up an excellent relationship with Liam. He disobeyed an order from the hotel management.

What was the order he disobeyed? It was not to take anything into Liams room. Because of the good relationship he had with Liam he requested a car through one of these taxi apps we all use because Liam wanted something. He did him that favour, a massive error because hes being investigated, and theyre seeing what was transferred in that vehicle.

Its one of the things the investigators are looking at at the moment and obviously this hotel worker has been suspended. Hes a cherished member of staff, a good worker, but he disobeyed an order that could have proved fatal.

Prosecutors said in a statement after Liams death they believed he was in in a state of semi or total unconsciousness during a substance-induced psychotic episode when he fell. The 31-year-old Brit died of multiple trauma injuries which had caused internal and external haemorrhaging. His 25 life-threatening injuries are believed to have included a skull fracture.

Investigators have indicated they do not suspect any third-party involvement but have made it clear the hunt is still on for his dealer amid speculation someone from his hotel was supplying him with narcotics.

Argentinian news portal Infobae reported last week forensic experts had discovered traces of cocaine in Liams body but tests on a white powder pictured in leaked photos showing the inside of his hotel suite after his death had so far proved inconclusive.

Other unconfirmed reports originating in the US claimed a cocktail of drugs including designer narcotic pink cocaine containing MDMA, ketamine, methamphetamine had been found in his system during a partial autopsy along with crack cocaine and benzodiazepine.

Last Thursday Buenos Aires police swooped on the hotel Liam died at and were seen going through documents and examining computers in the lobby. The singers dad Geoff flew to Buenos Aires after learning of the tragedy to try to speed up the repatriation of the singers body.

He was told during a meeting with prosecutor Andres Madrea last Tuesday that will not happen before toxicology and tissue tests are complete.
