According to the media outlet, the gunman who killed a police officer in Montrouge was acquainted with the Kouachi brothers, the alleged perpetrators of the terrorist attack on Charlie Hebdo magazine. The three are reported to have been part of the same jihadist network operating in the North-East of Paris.
Earlier, the police said the two attacks were not linked.
Brothers Said and Cherif Kouachi, French nationals of Algerian origin, who earlier had a connection to underground jihadi network transporting French radical Islamists to Syria, are suspected of carrying out the attack.
