Director arrested, large-scale pharmaceutical company raided.
Not only did the group working at NAC High-Tech Pharmaceutical Company Limited evade their tax obligations to the State, but they also impersonated doctors and medical staff from large, reputable hospitals to sell skin whitening and skincare products.
On October 3rd, the Hanoi City Police announced that they have initiated a criminal case for "Violation of accounting regulations causing serious consequences" at NAC High-Tech Pharmaceutical Company Limited (hereinafter referred to as NAC Company, located at 16 Van Hoi Street, Duc Thang Ward, Bac Tu Liem District).
The police also initiated legal proceedings and temporarily detained four suspects from NAC Company, including: Vu Dang Thai - Director; Nguyen Van Huy - Head of Sales Department; Hoang Manh Thang - Head of Marketing and Chatpage Department; and Hoang Thi Anh Ngoc - Accountant.
This group is the mastermind behind the act of creating two sets of accounting books, concealing hundreds of billions of dong from capital and revenue, causing exceptionally large losses to the State budget.

Previously, the Economic Police Department of Hanoi City Police discovered that NAC Company showed signs of concealing revenue to evade tax obligations to the State and impersonating doctors and medical staff from large, reputable hospitals to sell skin whitening and skincare products, so they launched an investigation.
The investigation revealed that, in order to conceal actual sales figures and evade taxes, Vu Dang Thai instructed his employees to use personal bank accounts instead of company accounts to directly receive payments for products or COD (cash on delivery) payments from shipping companies. The entire amount was then transferred to the personal accounts of Thai's family members.
Using this method, Thai and his accomplices kept hundreds of billions of dong in revenue from the sale of the company's melasma treatment products off the accounting books.
Thai and his accomplices used two accounting books to conceal actual revenue. One was a legitimate accounting book used for tax declarations and reports to deceive authorities during inspections (the declared figures were lower than the actual figures; for example, in 2023, actual revenue was estimated at over 51 billion VND, but the reported revenue for tax purposes was nearly 886 million VND); the other was an internal accounting book tracking the company's actual business operations and sales.
The calculated profit will be divided according to the shareholding ratio among Thai, Huy, and Thang.
Impersonating doctors at major hospitals.
In the case at NAC Company, the police also clarified that Thai and the other suspects took advantage of customers' reluctance to travel far for medical treatment and fully exploited the features of social media to boost sales.
The perpetrators devised various customer outreach scenarios and instructed company employees to use disposable phones and SIM cards to create fake Zalo and Facebook accounts, directly calling customers to share secrets for treating melasma.
To carry out their scheme, this group introduced themselves as doctors providing direct consultations to customers via Zalo and Facebook applications, or used these platforms to advertise Nacodi and Twhite products (products exclusively distributed by NAC Company). They posted numerous videos featuring dermatologists advertising the products and videos of "customers" sharing their secrets to using the products to treat their melasma.

The perpetrators also impersonated dermatologists at large, reputable hospitals to instruct customers to send photos of their facial pigmentation, then used photo editing software to diagnose the condition and prescribe treatment products.
After customers use the product, the perpetrators then ask them to send photos of their facial skin, which they then edit to show improved skin, reduced dark spots, and send back to the customers in order to build trust and exaggerate the product's effectiveness.
By continuously contacting and impersonating doctors to influence customers' psychology, the group sold a large quantity of Nacodi and Twhite products.
Based on the collected evidence, the police conducted simultaneous urgent searches of NAC Company's offices. At the time, NAC Company had over 60 employees who were making phone calls and providing advice to customers.
Currently, the Hanoi City Police are expanding their investigation to clarify the case, while also closely coordinating with the Hanoi City Tax Department to recover the tax money.
