A man who Sioux Falls Police say robbed the Executive Casino at 2218 S. Minnesota Avenue early Thursday morning had been playing the machines for about a half hour before he pulled out a pocket knife and demanded money.
That happened around 12:49 a.m.
He ran from the casino but another customer followed and watched him get into a late 90's Ford pickup truck. It was white with a topper, nice rims and had a brake light in the center of the rear window. It appeared to have been driven by a second man.
Police say the robbery suspect is white, in his mid 40's, was 5 feet, 5 inches tall and between 150 and 160 pounds. He had short, light brown hair and a mustache as well as a large tattoo on his left forearm and a smaller quarter-size tattoo on his right forearm.
The driver was also white, had a bushy beard and was wearing glasses.
