Nature: Adlène Hicheur, a French Algerian physicist working at CERN, was arrested in his hometown of Vienne, France, in October 2009 on suspicion of plotting attacks against French military targets and an oil refinery owned by the French firm Total. He’s spent the past two years in detention without trial or formal indictment. Swiss authorities closed their own investigation in the fall of 2010, stating that they found no evidence of wrongdoing, but French investigators extended the detention at that time. On 12 October the independent judicial investigation into the case will close, and prosecutors have one month after that to decide whether to try him or dismiss the charges.
