One of Kim Kardashian and Kanye West's former bodyguards, Steve Stanulis, opened up to ET about the recent robbery in Paris, revealing that he believes the assailants were tipped off.
Taking into account the slim window of opportunity (there were only two five-hour blocks of time where Kardashian was alone) and the swift way they snatched up the jewels, Stanulis believes that the robbers must have had inside information.
"To know the main security guy, who's a beast, is gone and you can walk right in with five guys and nobody will have the ability to stop you ... tie her up ... they know where the jewelry is," Stanulis tells ET. "It's not like they came in and were ransacking the place. They knew exactly where everything was. And then they leave on a bike, dressed as cops. Nobody says anything. It's either someone that works for them or that works for the hotel that's privy to their itinerary."
Kardashian's main bodyguard, Pascal Duvier, was with Kim's sisters Kourtney Kardashian and Kendall Jenner at the time of the robbery.
Duvier, who reportedly stands 6-foot-4-inches tall and weighs 264 pounds, has been working with Kim and Kanye since 2013, and was the man who took down infamous prankster Vitalii Seduik after he lunged at Kim last Thursday. According to his LinkedIn account, Duvier's client list also includes The Black Eyed Peas, Ciara, David Guetta and Frank Ocean. He has reportedly vowed to track down the men responsible for the robbery in a personal blog entry cited by the Daily Mail
Meanwhile, French police are looking for surveillance video.
"I think there was a getaway car maybe a block or two away at the most," Stanulis believes. "Those guys divvied that up and were out of the country before that night was over."
According to French Judicial sources who spoke with CBS Radio News, five people dressed as law enforcement officers went to where Kim was staying and got access to her room and robbed her. After tying her up and pointing a gun at her, the individuals robbed Kim of a reported $10 million worth of jewelry.
Now the famous family is trying to figure out how to prevent an incident like this from ever happening again.
A source tells ET that Kim and Kanye are "reassessing their security detail."
"Their immediate need is undercover security -- people who will be with them but stepped back to the side," the source adds. "There are plans for many other things they'll change as well."
