A fight broke out around 5pm on Wednesday at a Dutch-speaking Scout camp in the Durbuy community.
A scout was injured in the stomach, stabbed or damaged in a bottle, the floor says. Hospitalized in Marche-en-Famenne, he was still in intensive care on Wednesday night, but his vital prognosis was not involved.
A medical pathologist has been appointed to find the lesions and what the consequences will be.
Based on the medical report, the prosecutor will decide whether or not to submit the case to the investigation.
The offender, aged 18, was released from parole.
Another Scout was wounded in the battle. Slower, he could leave the hospital.
