The exchange vaguely discussed plans for terror attacks, but nothing concrete was planned, the French official said, speaking on condition that his name not be used because the investigation is ongoing.
French counterterrorism and intelligence agencies have been tracking Adlène Hicheur for 18 months by reading his e-mails, says the Independent
[Hicheur] was not a CERN employee and performed his research under a contract with an outside institute. His work did not bring him into contact with anything that could be used for terrorism: CERN is a particle-physics research laboratory whose research addresses fundamental questions about the universe. None of our research has potential for military application, and all our results are published openly in the public domain. CERN is providing the support requested by the French police in this enquiry.
Hicheur had previously worked on the BaBar experiment
