Authorities would not comment on if the two crimes were connected in any way.
Smyrna police arrested Terrence Robinson, 28, of St. Louis, on Thursday, charging him with felony robbery. As of press time, he was in the process of being booked into the Cobb County jail.
On Thursday, Smyrna police responded to a 911 call reporting a robbery at the Wells Fargo Bank on South Cobb Drive near the intersection of Concord Road Southeast at 9:45 a.m.
Police searched the area after witnesses described a man they say gave a bank employee a holdup note.
Police said they found Robinson at the Kroger across the street from the bank, and arrested him there.
They say they found Robinson carrying a bag of money from the bank.
On Wednesday, police arrested Kentrell Maurice Allen, 18, and charged him with attempting to rob a bank inside the same Kroger. Allen was booked in the Cobb County jail Wednesday afternoon. He was not granted bond.
Authorities say Allen was arrested after running away from Fifth Third Bank on South Cobb Drive, which is inside the Kroger on that street. Police said they responded to the scene at about noon after receiving a 911 call from a bank employee.
Nothing was stolen because the suspect left the scene before he could get any money, investigators say.
Police chased Allen, who fit the description witnesses had given them. When police arrested Allen, they searched his car and found a holdup note, which they said tied him to the robbery attempt.
Allen was charged with felony attempted robbery and misdemeanor obstruction of an officer.
