PARIS (Reuters) - A French judge on Wedesday (March 30) put under formal investigation a Frenchman arrested last week on suspicion of planning an imminent attack, Paris' prosecutor said.

Francois Molins said that the large amount of weapons, including assault rifles and handguns as well as chemicals that could be used for a bomb, had been found at Reda Kriket's apartment.

"Everything suggest that the discovery of this cache avoided a act of extreme violence by a terrorist network ready," Molins told a news conference, adding that Kriket was suspected of going to Syria end 2014.
