The Ho Chi Minh City Customs Department said Sunday its officers seized two rubber stamps made to imitate those used by a Vietnamese state agency that had been sent from Indonesia.
The officers found two rubber stamps in a package addressed to two persons in Da Nang City's Son Tra District.
One stamp imitates that of the Son Tra District Tax Bureau and the other replicates the stamp of the bureau's chief, Tran Khanh.
The package was sent by Tirta Bulan Bali PT Gita of Indonesia, the officers said.
The Son Tra District Tax Bureau said only authentic stamps are currently being used.
The HCMC Customs Department said the case is being investigated.
