Police said the suspect was apprehended near the city of Patra, some 130 miles west of Athens.
Five people were injured when an attacker started shooting at a social security agency in Petralona before travelling to a nearby courthouse in Ampelokipi, where he opened fire once again.
Police say the suspect fled the scene and left behind a shotgun.
He was described by witnesses as tall and thin and wearing a blue trench coat.
One of the people injured at the social security agency suffered shrapnel wounds to his legs and was taken to hospital for treatment.
The motive for the shooting is not yet known, but the gunman reportedly threw envelopes containing documents onto the floor of the courthouse, saying those were the reasons for the shooting.

Police are maintaining a heavy presence at both locations.
Alexandros Varveris, head of the National Social Security Fund, told local media that the attacker had gone to the fourth floor of the social security fund's offices in central Athens and told an employee "to duck" before he opened fire.
Mr Varveris told ERT radio that the gunman didn't seem to have specifically targeted the employee he hit.
The attacker reportedly entered both buildings with the shotgun concealed in his coat.
