The man is one of three suspects detained in connection with a triple murder involving members of the Outlaws bikers' gang of Maasmechelen in Limburg at the end of May. Two Outlaws and a third person were killed.
The suspect's lawyer says that a court set his client at liberty several weeks ago. Federal public prosecutors appealed against the decision that meant that the suspect had to remain in gaol. However, the appeal has not been dealt with within the fifteen days prescribed by the law. The lawyer now claims that his client is being illegally held in prison.
The matter will be heard by a judge in Tongeren on Monday.
