**France has arrested a researcher at the European Organization for Nuclear Research (Cern) for suspected links with al-Qaeda, officials have said.**The 32-year-old man of Algerian descent was one of two brothers detained in the south-east town of Vienne on Thursday.
Police believe they had been in contact over the internet with people linked to al-Qaeda in the Islamic Maghreb, and had been planning attacks in France.
Cern’s particle collider is aiming to recreate conditions of the Big Bang.
The organisation told the Associated Press that the researcher, whom it did not identify, was working for an outside institute and had no contact with anything that could have been used for terrorism.
Computers, hard drives and USB storage devices were removed from the brothers’ home after their arrest.
