French police believe the gunman who shot and seriously wounded a photographer Monday at the offices of the Liberation daily is the same suspect who threatened several BFM TV reporters last week with a shotgun, the newspaper said.

The shooter is described as a heavily built man of about 40 with a shaved head.

That information was not confirmed by police, who told Efe it was still "too early" to establish a link between the two crimes.

The shooter entered the lobby of Liberation's building in downtown Paris at 10:15 a.m. and fired at a photographer's assistant with a sawed-off shotgun.

The 27-year-old man sustained serious wounds to the chest and abdomen and was rushed to a hospital.

The shell casings found at the scene were the same type as those discovered at the Paris headquarters of BFM TV last Friday, when a man armed with a shotgun entered the building at 7:00 a.m. and threatened several journalists.

The gunman fled the scene without firing his weapon, but police found two .12-caliber shotgun shells on the floor.

Interior Minister Manuel Valls confirmed Monday that he had ordered the police to guard the offices of the capital's large media outlets as a precautionary measure.

"We can't downplay the reality of a hateful action of this type," Valls said outside Liberation's offices, where he was joined by Culture Minister Aurelie Filippetti and Paris Mayor Bertrand Delanoë.

Two hours after the attack at Liberation, a man fitting the same description fired at the headquarters of French bank Societe Generale, a skyscraper located in the La Defense business district on Paris' outskirts.

No one was injured but one of the building's windows was shattered. EFE
