Monday January 16, 7:15 a.m., 3, allée Nicolas-Poussin, Lochères district in Sarcelles (Val-d’Oise). Police are banging on the door of a ground floor apartment. “Hello, it’s the police, open up!” After a few minutes of waiting, the sleepy face of a man appears in the half-open door. “How many are you in the apartment?” asks the agent. “Twelve” lets go of the man with the hesitant voice, letting the police officers, those sworn in from the municipal hygiene and health service and those from the Regional Health Agency (ARS) enter the accommodation.
