A man is being held in custody in connection with the shootings earlier this week in Paris, it has been reported.
Paris prosecutors office said police had arrested a man bearing a "strong physical resemblance" to the gunman suspected of carrying out several recent attacks.
The man was arrested around 7pm local time (6pm GMT) in a vehicle in an underground parking lot in the western Paris suburb of Bois-Colombes.
French police had earlier said they had the DNA of the gunman suspected of carrying out shootings at two media organisations and a bank.
On Monday, the shooter critically wounded a photographer at the offices of major daily newspaper Liberation.
The photographer was arriving for his first day of freelance work at the newspaper and suffered wounds to his chest and stomach.
After fleeing the newspaper's offices in the east of Paris, the gunman is believed to have crossed over to the western edge of the city, where he fired several shots outside the main office of the Societe Generale bank. No one was hurt.
He then reportedly hijacked a car driven by a priest and forced him to drop him off close to the Champs-Elysees in the centre of the city.
The shootings prompted a massive manhunt across Paris.
