Five years ago, a Belgian teenager who had traveled to war in Syria was the leading prosecution witness in one of the largest terrorist trials ever held in Europe.
Jejoen Bontinck, a returne to Syria, testified against his former colleagues in the Islamist organization Sharia4Belgium, who said he had been brainwashed.
Now 25, he is looking to build a new life as a musician named Ready4Jerri.
He gave his first interview since the trial of our Brussels correspondent Nick Beake.
