Five years ago, a Belgian teenager who had travelled to the war in Syria, became the key prosecution witness in the one of the biggest terrorism trials ever held in Europe.
Jejoen Bontinck, a Syria returnee, gave evidence against his former friends in the Islamist group Sharia4Belgium, who he claims brainwashed him.
Now 25, he’s trying to build a new life as a musician under the name Ready4Jerri.
He’s given his first interview since the trial to our Brussels correspondent Nick Beake.
