French newspaper reports say that the suspect has admitted he was involved in the incident, but is playing down his role.
The Belgian is said to have been kicked full in the face. He is now in a coma and in intensive care in a French hospital. Lille prosecutors say that the Belgian responded to a call on the social networking website Facebook to gather outside a restaurant in the northern French city in order to celebrate the result of a soccer match.
