Police activity closed all lanes on I-75 Southbound before I-285 in Cobb County for about two hours Friday morning.
The incident happened when a "non-compliant" driver was stopped shortly before 10 a.m. The driver was believed to be armed, according to Marietta police.
Police believe the driver was involved in an armed robbery at the Walmart at 210 Cobb Parkway in Marietta, police spokesman Officer Chuck McPhilamy said in a statement.
“The vehicle and driver match the description of a suspect who committed an armed robbery in the city,” he said. “Within a short period of time, Marietta officers located the suspect vehicle and attempted to conduct a traffic stop.”
The suspect was taken into custody and lanes reopened by 11:30 a.m., according to the Georgia Department of Transportation.
