WATCH: Kim Kardashian Recounts Traumatizing Paris Robbery

Kim Kardashian is telling the story of her nightmare October Paris robbery.

In the sneak peek from an upcoming episode of Keeping up with the Kardashians, the reality star opened up about the experience, which took place on October 3, 2016. "They ask for money. I said, 'I don't have any money,'" she recalls. "They dragged me out to the hallway, on top of the stairs. That's when I saw the gun clear as day. I was kind of looking at the gun. Looking down back at the stairs."

She continues explaining the incident to sisters Kourtney Kardashian and Khloe Kardashian, detailing the moment she had to make a "split-second" decision when face-to-face with the thieves.

In January, 17 people were arrested who were connected to the armed robbery. One of the suspects was allegedly found because of DNA left on one of Kim's stolen pieces of jewelry that was dropped trying to getaway. Then, more details on the incident were revealed, saying the star was robbed at 4:30 a.m. while only wearing a bathrobe.

Kim K will recount the full story on this Sunday's episode of KUWTK at 9 p.m ET on E!
