Turin, November 29 - Nine people were placed under house arrest on Thursday in connection with protests over the construction of the controversial Italo-French high-speed rail link between Turin and Lyon. Two known anarchists were arrested for allegedly attacking a television crew working for the website of Italian daily newspaper Corriere della Sera in February. The attack took place near the Turin-Bardonecchia motorway in the municipality of Chianocco. Here a group of assailants prevented the crew from filming their report, seized their vehicle, documents and other items and damaged equipment. Seven members of local left-wing squats were also placed under house arrest over their alleged involvement in an August raid on the premises of a Turin engineering firm undertaking preparatory work for the railway line. Police carried out six property searches - two in Turin, two in Trento, one in Rome and one in Como - in connection with this episode too. Cautionary measures were also issued against 10 other people implicated in the two incidents, including residence bans and mandatory reporting to prison police. In addition, police on Thursday dismantled a shack built by protesters and sequestered a second outpost in the municipality of Chiomonte in Piedmont's Val di Susa, the epicentre of the protests. No-Tav activists have organized a series of protests against the high-speed rail link throughout Italy over the last few years. Some have included violent clashes with police and disruption of highway traffic. Opponents of the project contest its high cost and impact on the environment.
