McDonald’s headquarters is at McDonald’s Plaza, 2111 McDonald’s Dr.

Police said both men pulled handguns, and ordered employees to the ground.

The men demanded money from the registers and after they got an undisclosed amount of cash, they fled.

Since the robbery, police have been reviewing surveillance video, and are considering the possibility that the robbers are the same ones who hit the McDonald’s flagship restaurant on Aug. 14, the Daily Herald reported.

In that incident, the robbers pulled a long-gun on the cashier at the drive-up window, and made off with cash, the newspaper reported.

The sport-utility vehicle used in that robbery, a Toyota 4-Runner, was recovered, and turned out to have been stolen, the Daily Herald reported.

Anyone with information should call police at (630) 368-5060.
