A trick on the background of car rental and a pilfered deposit, a teenager who sends on Snapchat the photo of the young rascal who is also his classmate. And a punitive expedition punctuated with humiliations which ends with the payment of a “fine”, in other words a ransom of… 400 euros for the release of Yanis (all the first names have been changed), 17 years old. This teenager, a pupil of the Raspail high school (Paris XIV), lived through hell on May 20, 2022. For these facts, five high school students were tried at the end of January by the Paris juvenile court. Four of them have been found guilty and will be sentenced on September 27, 2023.
