A manhunt is continuing in Paris after a gunman attacked offices of the newspaper Liberation and fired outside the HQ of the Societe Generale bank.
A 27-year-old photographer was critically hurt at the paper on Monday. The gunman later forced a motorist to take him to the Champs Elysees, telling them he was armed with grenades, before allowing the driver to go.
Police are looking for the same man who broke into the Paris offices of the 24-hour news channel BFMTV on Friday. They have now been stationed outside all the main media offices in the French capital, the BBC reports.
At a news conference, investigators held up two images, one of the suspect in a street and another taken from BFMTV surveillance cameras on Friday.
Paris prosecutor Francois Molins said the "most likely possibility" was that a lone gunman was behind the three attacks and the hijacking. He said the suspect had not yet been identified and the motive was still unclear.
The man is said to be between 35 and 45 years old, between 1.7m and 1.8m tall (5ft 6" and 5ft 10"), with stubble and greying hair.
Mr Molins said the suspect was wearing a black vest, a cap and white-soled green shoes.
