A manhunt was underway in Paris Monday after a gunman opened fire at a newspaper -- seriously injuring a photographer's assistant -- then shot outside a bank before hijacking a car to escape, police said. The 27-year-old victim, who worked at a magazine for the Liberation newspaper was shot in the stomach and arm, NBC News reported. The first shooting took place in the lobby of Liberation's office at 10:15 a.m. local time and was followed by a shooting in front of Société General Bank in the west end of the city. Police then received a report that a driver was taken hostage by an armed man who fled on foot near the Champs-Élysées. Those shootings followed an earlier shooting Friday at the Paris news channel BFMTV.
