Police are scouring the city for the man responsible for several high-profile shootings. A lone gunman walked into the headquarters of the newspaper “Libération” yesterday and seriously wounded a photographer. He also opened fire at the office of the major bank Société Generale before hijacking a car and disappearing near the Champs-Elysees. Days earlier, the same man is believed to have broken into the offices of the news channel BFMTV and threatened the staff. Police have deployed outside other possible targets for fear he might attack again.
