Questions continue to arise about Kim Kardashian West's security chief Pascal Duvier


As questions persist surrounding Kim Kardashian West‘s security chief Pascal Duvier in the wake of her life-threatening robbery, one expert says the incident resulted from a “lack of professionalism.”

“Someone should have been outside the room. Someone should be monitoring the threat. Someone should have noticed any possible surveillance,” Christopher Hagon, a managing partner at Incident Management Group, a Florida-based international security consulting firm, tells PEOPLE.

“Someone should control the information that led to where she was. All of these things are symptomatic of a lack of professionalism.”

The 35-year-old reality star was held at gunpoint early Monday morning in her Paris hotel room when five masked men allegedly broke in and tied her up before making off with two cellphones and about $10 million worth of jewelry, including a $4 million ring.”

On Wednesday, a source told PEOPLE that the Keeping up with the Kardashians star is “more worried than ever” about her security. And as all eyes have been Kardashian West’s security team, namely Duvier, an insider told PEOPLE that the Spain-born German is still working for the family.

“Pascal still works for them,” the source said. “He isn’t irreplaceable though. The family really likes him, but he is not a family member … Kanye [West] is evaluating his family’s needs. he is ultimately the one who decides what happens with Pascal.”

Although he is still employed by the reality star, TMZ reported on Wednesday afternoon that Duvier deleted all traces of the star from his social media accounts as a safety measure.

However, Hagon, a former security officer for the royal family, says it was “unprofessional” of him to have photos of his client on his social media accounts in the first place.

“I just don’t think it’s professional,” the security expert tells PEOPLE, noting that it likely would not have posed a risk to her security. “You’ve got to keep your eye on the goal post here. The goal post is the protection and safety of the [client]. Anything that might detach from that is unprofessional.”

He adds: “If it was me, I would do my best to conceal myself.”

When the robbery occurred, Duvier was out with the star’s sisters Kourtney Kardashian and Kendall Jenner, which Hagon says is “symptomatic of a lack of attention to detail.”
