Around 2 a.m., officers received a call about two suspects robbing T-T Internet Sweepstakes Cafe on Crabtree Boulevard, near Capital Boulevard.
One of the suspects reportedly fired gunshots while inside, but no one was struck.
As the suspects fled the scene, authorities said they encountered a customer who had run out of the business during the crime. One of the suspects then shot the man, who was later identifed as 48-year-old Christopher Tyrone McElroy, in the abdomen before fleeing.
When officers arrived, they found McElroy in the parking lot. He was taken to WakeMed with non-life-threatening injuries.
Authorities are currently searching for the suspects.
The first suspect is described as an African American man standing between 5 feet 10 inches and 6 feet tall and weighing about 180 to 190 pounds. He was last seen wearing khaki pants, a white shirt and a tan hat.
The second suspect is also described as an African American man, standing between 5 feet 8 to 11 inches tall. He was last seen wearing a hooded sweatshirt with a "graffiti" print and jeans.
