A French physicist arrested last week while working at the world’s largest atom smasher has acknowledged to investigators that he corresponded over the internet with a contact in North Africa’s al-Qaida branch.
A judicial official said the e-mails vaguely discussed plans for terror attacks but that nothing concrete was planned.
The official spoke on condition of anonymity because the investigation is ongoing.
The 32-year-old Frenchman of Algerian origin was one of more than 7,000 scientists working on the Large Hadron Collider in Switzerland. He was one of two brothers taken into custody Thursday in south eastern French city of Vienne.
The judicial official said the other brother has been released.
