A lone gunman is believed to have carried out four attacks since Friday including a shooting in the Paris offices of a left-wing newspaper which has left one person seriously injured.
- A lone gunman enters the offices of 24-hour news channel, BFMTV, on Friday and reportedly fires two shots before declaring: "Next time, I won't miss."
- On Monday, a man enters the offices of left-wing newspaper Liberation in central Paris.
- He shoots and seriously wounds a photographer's assistant, who is fighting for his life, before fleeing.
- About 90 minutes later a lone gunman fired at least three shots into the lobby of the headquarters of Societe Generale - a bank. A window was shattered but nobody was hurt.
- A lone gunman then hijacked a car and forced the driver to take him to the Champs-Elysees area before vanishing into the crowd.
Paris prosecutor Francois Molins said: "Given the similarities between these four cases...we are favouring the hypothesis that there is one author. The suspect is of European type, with salt-and-pepper hair and possibly 2 or 3 days of stubble."
