The Paris prosecutor has lodged a preliminary charge against the suspect in a shooting spree at media offices and a bank.
In a statement, the prosecutor said Abdelhakim Dekhar was charged late on Friday with several attempted murders and a kidnapping lasting fewer than seven days.
Dekhar is the suspect in shootings at a television station, a newspaper office and a French bank. He is also believed to have forced a driver to take him into central Paris. In one of the shootings, a photographer's assistant was seriously injured.
After a two-day manhunt, police found Dekhar semi-conscious in a parking garage following a suicide attempt. Authorities found a letter with him that spoke of fascist plots and criticised media manipulation and capitalism.
Dekhar is being held in pre-trial detention.
