Investigators say it happened Dec. 7 when the duo caught a cab in the 6200-block of Capital Boulevard and asked the driver to take them to the 1100-block of Lehman Lane.
Once there, one of the men put a gun against the side of the driver while the other took his money. The driver was not hurt.

The second suspect is described as a black male in his teens to 20s with a thin build who stands about 6 feet to 6 feet 2 inches tall. He was wearing a dark colored sweatshirt with Duke written on the front.
