Yve Cresson, who works for a media production company in a building near the offices of satirical newspaper Charlie Hebdo, has been tweeting since the shooting about what he saw and heard.
According to Cresson's Twitter bio, he works for Bayoo, a media company whose offices are near Charlie Hebdo's on the Rue Nicolas Appert.
The first tweets described hearing gunfire:
Echanges de coups de feu rue Nicolas Appert 75011 autour du siège de Charlie Hebdo— yve cresson (@yvecresson) January 7, 2015
"Exchange of gunfire in Rue Nicolas Appert 75011 around the Charlie Hebdo headquarters"
des blesses chez Charlie, on craint pire— yve cresson (@yvecresson) January 7, 2015
"Injuries at Charlie, we fear the worst"
Cresson tweeted photos of ambulances taking away the wounded:
Cresson tweeted that the gunmen originally came to the wrong offices, apparently taking advantage of the mail carrier's arrival to gain entry:
a 11:25 profitant du passage de la factrice 2 H cagoules et armes sont entres dans nos locaux Il cherchait Charlie— yve cresson (@yvecresson) January 7, 2015
"At 11:25 a.m., taking advantage of the mail carrier's arrival, two armed men wearing balaclavas entered our offices. They were looking for Charlie"

"They shot twice. The bullets went through the door and the window"
2 H armes sont entres dans nos bureaux. Il cherchait #Charliehebdo ils sont repartis après avoir tire 2x— yve cresson (@yvecresson) January 7, 2015
Cresson later clarified that those shots were fired in his office: "Two armed men entered our offices. They were looking for Charlie Hebdo and left after shooting twice."
Cresson found it puzzling that the men didn't have the right address:
Question:les assassins avaient un calme de pros,mais n'avaient pas repéré les locaux de #CharlieHebdo Ils se sont d'abord trompé d'escalier— yve cresson (@yvecresson) January 7, 2015
"Question: the assassins were as calm as professionals, but hadn't located the offices of Charlie Hebdo. They took the wrong staircase at first"
Le repérage de #CharlieHebdo était très imprécis. Il se sont d'abord trompés de locaux et d'adresse— yve cresson (@yvecresson) January 7, 2015
"The scouting of Charlie Hebdo was very imprecise. They at first got the wrong premises and address."
Cresson also tweeted a photo of cartridge found in his office:
And he described what they were wearing: balaclavas and bulletproof vests:
les assassins étaient cagoulés et portaient des gilets pare-balles #CharlieHebdo— yve cresson (@yvecresson) January 7, 2015
