As Reported by TMZ:

According to the police report, obtained by TMZ ... Shantrice was trollin' at LAX nightclub at the Luxor on October 26 ... and met a guy named Joseph Hall ... who didn't know she was a call girl.

The two hit it off ... and Wilkerson told him that she had a "dream" of having sex on a pile of money.

Hall asked if $5,000 was OK ...  she agreed ... and the two eventually went back to Hall's apartment to grab the cash out of a safe.

According to the report, the two bounced to Wilkerson's pad to do the deed ... but before it went down, Wilkerson asked for money ... and Hall flipped out and left.

But cops say, Wilkerson REMEMBERED where Hall lived ... and brought Grtis to the place 3 days later so they could rob it.

According to the report ... Grtis entered the pad with a gun ... and ordered Hall's roommate into the bathroom while he and the hooker stole a safe, 2 iPads, 2 laptops, passports, and anything else that wasn't nailed down.

Ivey is being held without bail and is due to face a judge on Monday.
