Authorities discover 10 homemade firearms at the residence of Nguyen Van Tuan known as Cuu Tuan Cua Ong amid ongoing criminal proceedings

The investigative division of the Quang Ninh City Police has significantly expanded its inquiry into the case of Nguyen Van Tuan, a 55-year-old resident of Cua Ong Ward, widely recognized on social media platforms under the moniker "Cuu Tuan Cua Ong." During a comprehensive search of the suspect’s residence, law enforcement officers uncovered a cache of ten homemade firearms, specifically categorized as marble-shooting guns, alongside a substantial quantity of ammunition and specialized manufacturing machinery. This discovery marks a critical escalation in a case that began as an investigation into the dissemination of misinformation and the exploitation of social media to infringe upon the legal rights of individuals and organizations.
Chronology of the Investigation and Recent Developments
The legal troubles for Nguyen Van Tuan reached a breaking point on November 4, 2026, when the Quang Ninh City Police formally initiated criminal proceedings against him. Authorities issued a decision to prosecute and subsequently ordered the temporary detention of the suspect. The charges brought against Tuan fall under Clause 2, Article 331 of the Penal Code, which pertains to the "abuse of democratic freedoms to infringe upon the interests of the State, the rights, and legitimate interests of organizations and individuals."
Following his arrest, investigators conducted a thorough search of Tuan’s primary residence and associated property. The raid resulted in the seizure of not only the ten improvised firearms and a significant stockpile of ball-bearing ammunition but also an array of computer equipment, manufacturing tools, and digital storage devices. These items are currently being processed by forensic experts to determine the extent of his production activities and whether the weapons were distributed or intended for criminal use beyond personal possession.
The Rise of "Cuu Tuan Cua Ong" on Social Media
Before his arrest, Tuan had established a prominent, albeit controversial, presence across various digital platforms, including Facebook, TikTok, YouTube, and Zalo. Operating under the name "Cuu Tuan Cua Ong," he gained notoriety by conducting live-streamed sessions that blended fortune-telling, astrology, and social commentary.
According to preliminary findings by the investigative authorities, Tuan utilized these platforms to disseminate a series of videos characterized by the presentation of unsubstantiated information. His content frequently targeted public figures, entertainers, and private individuals, focusing on their personal lives, relationships, and professional reputations. By leveraging sensationalism and the viral nature of algorithmic social media, Tuan managed to accumulate a substantial following, which he used to project his influence while simultaneously eroding the dignity and privacy of those he discussed.

Implications of the Illegal Weaponry Seizure
The discovery of manufacturing equipment for marble-shooting firearms adds a layer of severity to the existing criminal charges. While Tuan was initially detained for social media-related offenses, the possession of tools capable of mass-producing lethal or semi-lethal weapons suggests a potential underground operation.
In many jurisdictions, the production and distribution of homemade firearms pose a significant threat to public safety. These weapons, often built from readily available parts, bypass the rigorous regulatory oversight required for legal firearms ownership. The seizure of multiple units, coupled with the specialized equipment found on-site, raises questions regarding whether these weapons were being sold or distributed to third parties. The police are currently conducting a forensic audit of the seized computers to trace any digital footprints related to potential weapon sales or communications with prospective buyers.
Legal Framework and Penal Code Context
Article 331 of the Penal Code serves as a vital legal instrument in Vietnam for maintaining order in the digital space. It is designed to address instances where the right to free expression is weaponized to inflict tangible harm on others. In Tuan’s case, the invocation of Clause 2 suggests that authorities view his actions as having "serious consequences."
Legal experts note that the combination of online defamation and the possession of prohibited weapons significantly complicates the suspect’s legal standing. If the investigation concludes that the firearms were used to intimidate, threaten, or harm individuals targeted in his videos, Tuan could face additional charges under laws related to illegal weapons possession and potentially public order offenses.
During his initial interrogation, Nguyen Van Tuan reportedly acknowledged his involvement in the activities identified by the police. He has expressed remorse for his actions and has formally requested leniency from the legal authorities. However, the investigation remains in an active phase, with police continuing to gather evidence to determine if other individuals were complicit in his operations.
Broader Impact on Digital Content Regulation
The case of "Cuu Tuan Cua Ong" reflects a growing trend of law enforcement agencies intensifying their oversight of social media influencers and content creators who operate outside the bounds of professional journalism and ethical standards. In recent years, the rapid growth of platforms like TikTok and YouTube has led to a surge in content that prioritizes sensationalism over factual accuracy.

The Quang Ninh City Police Department has emphasized that this investigation serves as a warning to those who use digital platforms to spread misinformation or engage in illegal activities. The integration of "cyber-policing" with traditional criminal investigations highlights a shift in how authorities address threats that originate online but manifest in the physical world through harassment, privacy violations, or, as seen in this instance, the production of illicit hardware.
Next Steps in the Judicial Process
As the case moves forward, the primary focus for the investigative team will be the analysis of the digital evidence seized from Tuan’s property. This includes:
- Digital Forensic Analysis: Reviewing communication logs on the seized computers and mobile devices to identify if there were organized efforts to monetize the weapon manufacturing process.
- Victim Impact Assessments: Formalizing complaints from the individuals targeted in Tuan’s livestreams to establish a clearer picture of the harm caused.
- Weaponry Testing: Ballistics experts will examine the ten seized firearms to determine their kinetic energy and potential lethality, which will influence the final sentencing recommendations.
The Quang Ninh City Police have pledged to conclude the investigation thoroughly and transparently. As of mid-November 2026, the suspect remains in custody. The public and the legal community are awaiting further updates as the authorities determine whether Tuan acted alone or as part of a broader network involved in illegal weapon production and digital harassment.
Conclusion: A Warning to Digital Actors
The arrest of Nguyen Van Tuan is a stark reminder of the intersection between digital influence and legal accountability. While the internet offers an unprecedented platform for expression, the rights associated with that freedom are not absolute and are subject to the boundaries established by the law. By blending the distribution of harmful content with the physical manufacturing of illegal weapons, Tuan has crossed a threshold that has drawn significant scrutiny from state security apparatuses.
As this case progresses, it will likely be cited as a precedent for how authorities handle individuals who leverage digital fame to undermine social stability. For the public, the situation underscores the importance of media literacy and the necessity of critical thinking when consuming content from self-proclaimed influencers who operate without oversight or accountability. The ongoing investigation by the Quang Ninh City Police remains a matter of significant public interest, serving as a deterrent against the unchecked misuse of online platforms.
