Detention Act Article 71

Where a detention center discovers while conducting inspections money or items held by a defendant without permission, the detention center may turn them over to the national coffers, destroy or discard them, or take other appropriate actions in view of the circumstances. The same shall apply to money or items with unknown owners.
