It reported he had been "convulsing" in the lobby in the hour leading up to his death.

A close friend of Kate's has now told Page Six about the impact of the pictures on her pal: "(They show) he could have been saved, he could have been helped. "It's devastating - and infuriating. Whenever it seems it can't get more painful for Kate, it gets even more painful."

Actress Kate, 25, was with Liam until 48 hours before his death when she left heir extended holiday in Argentina to return to her home in the US.

The footage published by the Mail appears to show two hotel guests walking by as three men, two of whom are dressed in suits while a third carries a backpack carried Liam.

They were apparently hotel employees, but the CasaSur has not commented on the images.

The men in the video appear to have brought Liam to his third-floor room at around 4.54pm local time.

It's not clear why they did not get him medical help in the lobby.

Liam's funeral at St Mary's Church in Amersham, south-east England, was used to mark his legacy as a big-hearted donator to children's charities.

Philanthropic Liam gave away tens of thousands of pounds of his showbiz fortune, and the order of service at his final goodbye showed his family is directing all donations left in his name to the Great Ormond Street Children's Hospital - with the money set to used to help construct a new cancer unit on its famous London site.
