The 19-year-old was detained in the eastern Bas-Rhin region last Wednesday on suspicion he was preparing attacks during the upcoming Paris Olympic Games. According to security sources, they noticed threats against the Paris Olympics on a group named "French Aryan division" on the phone application Telegram; including death threats and hate speech.

The Paris public prosecutor’s office said in a statement he was convicted after a swift trial overnight Friday on charges of sharing bomb-making instructions on social media, posts inciting hate and death threats as well as posts with personal information that put people at risk. 

The prosecutor’s office clarified his alleged comments that triggered the probe by its unit, dedicated to fighting online hate, didn’t specifically target the Paris Olympics. 

France’s Interior Minister Gerald Darmanin said anti-terror police detained the man on suspicion of “a willingness to intervene during a stage, evidently, of the torch relay.”

The relay is nearing the end of its months-long trip around France and overseas French territories before the Games' opening ceremony. French security forces have already begun locking down central Paris in preparation for the Olympics with 45,000 officers, 1,900 foreign police, 10,000 French soldiers, and thousands of private security agents involved.
