Mayor Marc-Jean Ghyssels earlier confirmed reports that first surfaced in the Francophone daily La Dernière Heure. The team under investigation has meanwhile been suspended. The team leader will appear before a closed meeting of councillors on Tuesday, but councillors are only expected to impose a sanction next November.
The workmen stand accused of staging barbecues and serving alcoholic beverages amid the graves. They allegedly "played" with the bodies too.
Mayor Marc-Jean Ghyssels: "We regret what happened, especially for the families of the deceased. We acted as soon as we got a whiff of what was going on."
The matter first came to light after, during a separate disciplinary about rosters, a fellow worker made mention of the goings on.
