France arrests teenager suspected of attack plan

France's domestic intelligence service on Tuesday arrested a 15-year-old, suspected of preparing an attack in the name of Daesh ideology, a source close to the case told AFP.

The DGSI intelligence service became aware of the teenager because "he was clearly convinced by the theories of Daesh", the source said.

The teen was apprehended in the early hours of Tuesday in his home in Rosenau, a village of 2,400 inhabitants in the east of the country.

"He was determined to make explosive devices," the source said.

The ongoing investigation had shown that the teenager had already made some such devices, it said.

Investigators were now trying to establish whether there was a concrete attack plan and if so, how advanced it was.

The Le Parisien daily said anti-terror judges had opened a preliminary investigation into a possible "terrorist conspiracy".
