SIOUX FALLS — Police arrested a man on Thursday, Feb. 2, who is suspected of robbing three casinos and a convenience store over three days last month.

The Sioux Falls Area Joint Fugitive Task Force found Domach Kong Khai, 31, outside an apartment building in the 4000 block of East 12th Street about 2:50 p.m. on Thursday, Feb. 2.

“They saw him come out of the building and he was arrested on warrants,” police spokesperson Sam Clemens, said during the department’s regular briefing on Friday, Feb. 3. “There were no issues.”

The robberies took place at three casinos and one gas station over the course of five days in late January.

Authorities say that on Jan. 20, Khai entered a Get-n-Go gas station in the 2200 block of East 10th Street, where he displayed a knife, got cash and left. Later that same day, and across town, Khai is accused of entering the Paradise Casino in the 5100 block of West 12th Street, obtaining cash and leaving. No weapon was displayed in that robbery.

Throughout the week, police believe Khai also robbed the Neon Casino in the 4100 block of East 10th Street on Jan. 22 and the Boxcar Casino in the 1400 block of East 10th Street on Jan. 25.


Police used surveillance video and a description of a car used in the robberies to identify Khai before issuing the warrant for his arrest on four counts of robbery and two counts of aggravated assault. He’s being held on a $100,000 cash bond.
