As a teenager, Jejoen Bontinck danced in music videos and was a regular kid hanging out with friends in Antwerp, Belgium. But within a year, he went from a hip-hop-loving teenager to a young Muslim convert, preaching on the streets of Antwerp. His father, Dimitri Bontinck, claims that in 2010, when Jejoen was 15, he became infatuated with a Moroccan girl, which eventually led to him converting to Islam. His parents started noticing a radical change in their son about eight to nine months after the conversion. "He started to become very religious. He stopped wearing his normal clothes. So we really see the progress of radicalization -- this is the right word -- we really see the signs," Dimitri explained.
