Authorities say the suspect robbed the man of cash and fled the scene. The victim was not injured.
The suspect has been described as a black man in his teens to 20s, with "chubby" cheeks and a short, stocky build. The suspect was clean-shaven and was wearing a black puffy jacket and a black toboggan.
Based on the latest description, authorities say it appears to be a different suspect from another robbery that happened last week.
Last Tuesday, a couple was robbed in the parking lot near Pei Wei Asian Diner on Little Brier Creek Lane.
Barry Kyu says the robber went after his wife's purse first.
"The individual pulled the purse at gunpoint and then pointed the gun at me and asked for my wallet," Kyu said.
About 30 minutes after Kyu and his wife were robbed at gunpoint at Brier Creek, one of the suspects showed up at a convenience store on Riddle Road and Highway 55 in Durham. The suspect tried to use Ms. Kyu's credit card at an ATM and was caught on surveillance video.
There have been several armed robberies in the Brier Creek area since September.
Two people have been robbed at gunpoint at banks in Brier Creek, while getting out of their cars carrying money deposit bags.
One happened earlier this month at Bank of America and the other happened in November at Wachovia.
Raleigh Police believe the bank robberies are related, but are not sure if the robbery, Tuesday, last week or a September purse snatching at Lowes Foods in Brier Creek may involve the same suspect or suspects.
Raleigh Police continue investigating.
"We're out here for extra security, try to keep people safe, try to keep the calls down," Raleigh Police Officer CR Pierce said.
They have increased patrols in the area and they're asking anyone with information on the crimes to call Raleigh CrimeStoppers at (919) 834-HELP. CrimeStoppers pays cash rewards for anonymous tips that help solve cases.
Meanwhile, investigators are also working to figure out if a Durham robbery is connected to those in Brier Creek.
Durham Police say five men between the ages of 17 and 20 robbed a man at gunpoint in the parking deck right next to the movie theater at Northgate Mall Monday night.
Authorities say they were told two of the robbers had handguns and they got away with the victim's wallet.
No one was hurt and police haven't caught the robbers.
