This happened back on May 24th at the Net Clicks cafe near 35th Avenue and Dunlap.
Authorities say the suspect showed an employee a handgun, then demanded money. The victim complied and placed the cash in a bag.
Police say it was an odd place to hold up and they're looking into all possibilities.
"Maybe he had some inside knowledge about what kind of money they had on hand there.. or what kind of money they produce on hand... or maybe he's a former employee," said Phoenix Police Sgt. Derek Elmore.
The suspect is described as a white male in his mid-20s, 5' 9", 140 pounds, with brown hair and green eyes. He was clean shaven with a scar on the top of his head, which police say is a good clue to finding out who he is.
