Paris on alert as police hunt for armed suspect French police have launched a manhunt for the suspect in a shooting at the Paris headquarters of newspaper Libération - and another outside bank Société Générale, less than two hours later. One person was seriously injured when the gunman burst into the Libération's office and opened fire. No-one was injured outside SocGen, according to the firm. The authorities believe the suspect in both shootings was the same man who broke into the Paris offices of television news channel BFM on November 15. The police released video footage recorded by security cameras during the BFM incident to appeal for information to help identify the suspect - who they described as a "European-looking" 35 to 45-year-old. The police also said they believed that the same man was responsible for a carjacking soon after the shooting outside SocGen. In that incident, a gunman forced a motorist to drive him to the Champs-Élysées before letting him go. Paris Prosecutor François Molins told reporters: "We have to note the similarity of the four cases - in the modus operandi, how he was dressed, and the munitions too. Plus the fact that it was a lone aggressor in each case gives us a clue. Media outlets across Paris have been put under police protection, following the stormings of the offices of both a newspaper and a television channel in the capital.
