The Iraqi has been under investigation since he arrived here. He first moved in with his brother-in-law and then moved on, but left behind a camera containing images of him as a jihadi fighter in front of an IS flag.
An IS flag was recovered from among his personal possessions at the asylum centre in Jumet too. An examining magistrate decided on his arrest last Friday.
The suspect appeared before a judge on Wednesday and claimed that the pictures had been taken to avoid trouble in Iraq. He said he hoped that his family that is currently in Iraqi Kurdistan could join him soon.
