The lab and a fire expert went to the scene, and the clothes and mobile phones of the suspects were confiscated, they added.
Based on the results of further investigation that are currently being carried out, the public prosecutor will decide what will happen with the suspects next, within the 48-hour deprivation of liberty period.
A task force will be set up, composed of members of the six Brussels police zones, the federal police and the Brussels public prosecutor’s office to identify as many culprits as possible.
In addition to these four judicial arrests, 112 others were also administratively arrested, 30 of which were minors, during the riots on Wednesday.
Barrie died on Saturday 9 January about an hour after he was arrested by the Brussels North police. Upon arrival at the police station, he lost consciousness and the present police officers called the emergency services to take him to the hospital, where he died soon after.
In the meantime, the results of the autopsy, revealed by the family’s lawyer, have shown that Barrie died of heart failure.
