GRASSE, FRANCE — A teenage student entered a high school in southern France on Thursday and opened fire on his classmates and the headmaster, injuring at least four people. <br /> <br />The suspect reportedly entered Alexis de Tocqueville high school in Grasse, France on Thursday, armed with a rifle, two handguns and two hand grenades. Upon entering the cafeteria at roughly 12:40 p.m., witnesses said the gunman opened fire, causing terrified students to rush for the exits and hide under desks. <br /> <br />The gunman fired several gunshots, wounding three of his classmates. The school’s headmaster attempted to intervene, and was also hit with a gunshot to the arm. None of the injuries sustained are considered life threatening. <br /> <br />The gunman was arrested by police within minutes of the attack, and did not show any resistance. <br /> <br />The suspect has been identified as Killian Barbey, 17, the son of conservative French politician Franck Barbey. <br /> <br />The motives for the boy’s shooting spree are unclear at this time, but Barbey’s Facebook page suggests a fascination with firearms, and mad men, with several posts dedicated to Batman comic book villain The Joker. <br /> <br />He is said to have been obsessed with American high school shootings, such as the 1999 Columbine massacre in Colorado that claimed the lives of 12 students and a teacher.
