During recent regular inspections of CTT Macao, letter post items suspected of using forged postage certificates were found in the area around Praia do Manduco. These letter post items were not delivered by the postman of CTT Macao, but were found in the mail boxes of buildings or streets. Besides, these items were stamped with date chops, “Bulk Mail” and “Postage Paid” postmarks that are not in the format of CTT Macao. In addition, information of the sender and recipient was not indicated clearly too. CTT Macao already reported the founding to police and the public is advised to pay attention to the situation.
