Kim Kardashian West was dragged out of bed and had tape tied around her entire head as robbers snatched jewellery worth $8.5 million from her room earlier this month.
The 'Keeping Up With the Kardashians' star was left fearing for her life when a five-men gang broke into her room at Hôtel de Pourtalès in Paris, France, on October 3, waved a gun in her face, gagged her and tied her up in the bathroom while they raided her drawers.
The concierge on duty, who led the robbers to Kim's room, explained: "One of the gang kept telling her to shut up. I put my hand on her shoulder and told her to be calm.
"I said, you have to be silent, you know. She sat down on the bed. She asked me, 'Are we going to die?' I said, 'I don't know, how can I know?' She said, 'I have family and babies'. I told her, me too, I have one son. And she began to scream again. That's why he put the tape on her mouth. A long piece of tape, all the way round her head."
The traumatised guard - who is only known by his first name Abdulrahman for security reasons - initially tried to put the robbers off by claiming he didn't know who the 35-year-old star was before he was marched to her room "by the scruff of his neck".
Speaking exclusively to the MailOnline, he said: "We got to her bedroom and slid open the door. She was in her bed. Before we opened the door, she heard a noise and began to say, 'Hello? Hello?' I assume she thought it was her sister.
"The intonation of her voice changed when there was no answer, I felt she was worried. After that, one of them opened the door. The other one was fastened to me. He attacked her, holding his gun in her face.
"She was crying, she was screaming, saying, don't kill me, I have babies, don't kill me, please, I have babies! I'm a mom! Take whatever you want! She seemed terrified. She was wearing a white bathrobe and her hair was tied up."
Her bodyguard Pascal Duvier- who is also involved in the investigation - was out protecting her sister Kourtney Kardashian when the incident took place in the early hours.
An instructing judge is now leading more than 100 judicial police and officers from the Paris criminal brigade in the hope of catching the five-man gang.
The criminals will face charges of armed robbery by an organised gang, criminal conspiracy and kidnapping, which could lead to a sentence of at least 30 years.
Inmates sentenced to life in the European country are required to serve a safety period of at least 18 to 22 years before they can become eligible for early release.
