The pub is called Le Blue and is situated in the Overpoortstraat in Ghent, an area where many students go out. He had earlier convictions for breaking noise nuisance rules.
As the man continued to play loud music, the judge ordered his arrest. Last Friday, the landlord was apprehended in his pub. He will launch an appeal against his latest conviction.
