LIAM Payne fell to his death just minutes after hotel staff made a panicked call to 911.
The former One Direction heart-throb, 31, died instantly after tragically falling from his third-floor balcony on Wednesday.
At 4.26pm, Liam was pictured by another guest laying on a sofa in the lobby on his laptop.
Two minutes later he was snapped by a lift in the CasaSur Hotel lobby in Buenos Aires, Argentina.
Concerned hotel staff then dialled 911 at 5.01pm asking for police to be sent.
The head of reception said they needed "urgent assistance" to help with a guest "behaving erratically".

But they were faced with a grisly scene when they found Liam had fallen from his balcony into the hotel's inner courtyard.
At 5.07pm, police reported a person had plunged from the third floor and urgently requested an ambulance.
Paramedics arrived at the scene at 5.11pm local time (9.11pm UK time), and Liam was tragically pronounced dead.
It is unclear exactly what time dad-of-one Liam fell.
Witnesses have since claimed Liam was seen arguing with a mystery woman just three hotels before his death.
Michael Fleischmann, who was also staying at the hotel, claims the star was "very upset" as he argued about money in front of other guests.
Another guest said Liam displayed "disturbing" behaviour shortly before he died.
Investigators are now trying to piece together what happened to Liam before his fatal fall.
At least three hotel staff and two women who saw Liam the day he died have been spoken to by cops.
Police said they found his room in "complete disarray" with various items smashed and medication scattered around.
They said the circumstances surrounding Liam's death were suspicious and possibly involved drugs.
They insisted there was no sign of third party involvement, however.
Buenos Aires police said they found packs of a prescription drug, energy supplements and other over-the-counter medications strewn about his belongings.
The Argentine public prosecutor said there also appeared to be alcohol and narcotics in the room.
An autopsy revealed internal bleeding and 25 traumatic injuries to his skull, limbs and abdomen, which were enough to cause his death.

The lack of defensive injuries on Payne’s hands indicated that he may have fallen into a state of unconsciousness, the public prosecutor said.
Results of toxicology tests are pending and could take weeks to become public.
