Anti riot police throws tear gas as people gather in Bobigny, northern Paris, on February 16, 2017 during a demonstration to demand justice for Theo, a 22-year-old youth worker who required surgery after his arrest last week in the gritty suburb of Aulnay-sous-Bois. French President Francois Hollande called for "justice" over the alleged rape of a black youth with a police baton, an incident that has sparked 10 nights of rioting and more than 200 arrests. / AFP PHOTO / Philippe Lopez
