On April 19th, 2015, a student, Sid Ahmed Ghlam, was fortuitously arrested after a murder while he was planning a shooting in the churches of Saint-Cyr-et-Sainte-Julitte and St. Theresa during a Sunday Mass. According to the priest of Saint-Cyr-Sainte-Julitte, the arrest prevented a massacre, since 300 hundred people were present in the church on that day. Villejuif had already been targeted by Islamist terrorist Amedy Coulibaly during the January 2015 attacks.
