FILE - In this Friday, June 27, 2014 file photo, people gather at the Pierrefitte Town Hall, north of Paris, in a show of solidarity with a Roma teenager who was left bleeding and unconscious in a grocery cart by the side of a highway. It looked like any shantytown the world over — tarps to keep out the weather, scattered bits of trash that no truck would ever collect, plastic buckets to lug water. Then one of the inhabitants of this Roma camp on the northwest edge of Paris, a teenage boy named Darius, was beaten into a coma, apparently by residents of a neighboring housing project. Within hours, the Roma vanished, seeking sanctuary in a new location on the fringes of one of the world's wealthiest cities. Three weeks later, 16-year-old Darius remains unconscious. His family is in hiding. Police have made no arrests. France is coming under increasing pressure to answer allegations that it is encouraging harassment of Europe's poorest minority group in hopes that the Roma, also known as Gypsies, will leave the country.
