Concert goers were told “You’re all going to f***ing die” less than an hour before the Las Vegas shooting started, it has been claimed.

A woman in the crowd is said to have yelled the warning about 45 minutes before the Route 91 Harvest festival became the venue for the worst mass shooting in US history.

After her outburst, it was claimed, the woman and her male companion were made to leave the venue by security.

Less than an hour later, an attack began that left at least 50 people dead.

Witness Brianna Hendricks, said the woman had been behaving strangely before her outburst.

Ms Hendricks, who had been in Vegas to celebrate her 21st birthday, told Mail Online: “There was a lady who came running up behind us in the concert and she started to play with people's hair, acting crazy, and she told us that we're all going to f***ing die.

“She said they're all around us and we were going to die.”

Ms Hendricks said the woman had claimed her boyfriend could not breathe in order to push her way through the crowd to the front row.

She said: “It seemed she was telling us to either warn us, or she was part of it and she was telling us because she knew we were going to die. It was so scary.

“It felt like she had knowledge of what was about to happen.”

Ms Hendricks returned to the Mandalay hotel about 15 minutes before the shooting, and witnessed the subsequent carnage from her hotel room.

“It makes me feel uncomfortable,” said Ms Hendricks. “I thought it [the woman’s warning] had a correlation [to the shooting].”

She described the woman who gave the warning as “Hispanic, probably about 5ft 5, [with] brown hair”, and said the woman’s boyfriend was also Hispanic.

The authorities have yet to comment on whether the woman’s warning was just a bizarre coincidence, or whether it actually did have something to do with the mass shooting.

After the suspected gunman Stephen Paddock, a 64-year-old white man, was confirmed dead, police said they had also located his room-mate Marilou Danley.

Earlier, when appealing for information to help locate Ms Danley, police described her as 62 years old, Asian, 4 foot 11 inches tall and weighing 111 pounds (50 kg).

When announcing that Ms Danley had been found, Clark County Sheriff Joseph Lombardo made no comment on whether she was alive or dead.
