Who Is Kim Kardashian's Bodyguard Pascal Duvier and Where Was He at Time of Paris Robbery?

Kim Kardashian West's bodyguard was not with the reality star when she was robbed at gunpoint on Sunday night in an apartment she was staying at in Paris, France, but he was still hard at work.

A source tells ET that Pascal and the driver dropped Kim off at her apartment through the garage and Pascal went back out with Kourtney Kardashian, who met up with their sister, Kendall Jenner. Kourtney was staying with Kim at the apartment, while Kendall was at the Four Seasons hotel.

"No security was there in the apartment with Kim when [the robbery] happened," the source claims. "The bodyguard usually stays with them at the apartment, but he was with Kourtney when [it] all went down.”

Pascal was, however, with Kim when she arrived with husband Kanye West and mother Kris Jenner back at the couple's New York City apartment. Last week, he was also the man who took down infamous prankster Vitalii Seduik after he lunged at the 35-year-old star last Thursday.

"My security @PascalDuvier is a G," Kim tweeted after the incident.

Like Kim and her sisters, Pascal is also quite active on social media, though he has not tweeted or posted anything on Instagram since the robbery.

The bodyguard appears to respect the Kardashians' privacy quite a bit, as the tweet pinned to the top of his Twitter account reads: "Who ever asks me to deliver a message to a client of mine will be muted and blocked. I'm sick of that sh*t!! I'm not a messenger!!"

Pascal's background as a bodyguard is quite extensive. According to his LinkedIn account, his client list includes The Black Eyed Peas, Ciara, David Guetta and Frank Ocean. He has been to Iceland, Cuba and Armenia with Kim and her family, and at times can be spotted on Keeping Up With the Kardashians. Pascal -- who rarely leaves the house without a fanny pack -- has been working with Kim since 2013 and Kanye since 2012.

Pascal has also worked a series of tours for different artists, including Kanye and Fergie, and has protected people at the GRAMMYs and the Golden Globe Awards.

In addition to protecting celebrities, he is also the CEO and Chairman for Protect Security, and has two daughters.
