The Trấn Biên Ward Police’s response to a Facebook post about E10 gasoline has led to sizable public backlash.
The Latest: On June 5, the Facebook page of the Trấn Biên Ward Police in Đồng Nai City sparked intense public backlash after posting a message mocking residents who shared videos of themselves shaking their vehicles to mix E10 gasoline.
Following significant criticism and over 2,300 reactions—predominantly laughing and angry emojis—by noon on June 7, the post was hidden or removed from the page.
However, multiple users had already captured screenshots of the original post and its controversial comment section, which continue to circulate widely online.
The Details: The Facebook page of the Trấn Biên Ward Police, a page with more than 23,000 followers, published a post stating:
“If you see any bro or sis in Trấn Biên Ward making clips about ‘shaking the vehicle before starting it,’ please tag Admin. We mainly want to invite them to the ward office to learn from their clip-making experience. Promise, no testing.”
In the comment section, the page administrator elaborated that individuals would be invited so the police could learn video editing, while also “teaching a class so people can go online confidently and safely for their wallets, because copying whatever others do without understanding the matter can be costly.”
When users strongly opposed the post and the administrator’s tone, the Trấn Biên Ward Police page responded:
“Many fake accounts are coming in to steer public opinion. They are all anti-state elements, so Admin will block some of them, folks. This crowd gets paid enough for Coca-Cola and pork sausage for every comment like that, so they are very aggressive. They keep asking questions just to find a loophole and swarm in to ‘bite’ for Coca-Cola and pork sausage. Nothing good about them.”
Social Media Backlash: Across social media platforms, many users strongly criticized the post by the police.
- On June 6, a Facebook account named Nguyen Dan shared a screenshot of the post and stated:
“Here it is. This page claims to be the official information page of Trấn Biên Ward Police in Đồng Nai City, and yet it speaks like this. I do not know what to say anymore.”
- The following day, on June 7, Facebook user Vũ Huy Hoàng described the post as
“…the product of idle people deliberately insulting the public for malicious purposes. The people’s public security force is paid with taxpayers’ money and cannot possibly speak in such an ignorant, ill-mannered, vile, insolent, and arrogant tone.”
- On the platform Threads, an account named tmquan posted a screenshot and wrote:
“It is something else when even the police make these kinds of threats. After leaking citizens’ personal ID information, now this. Anyone shaking their vehicle should be careful.”
This post quickly garnered more than 3,000 likes, alongside hundreds of comments and shares.
One of the most widely engaged comments, which received over 400 likes, read:
“The more posts like this appear, the more they show that the police force is becoming arrogant, ignorant of the law, or contemptuous.”
Luật Khoa Magazine noted that they wrote out abbreviations from the original social media posts.
The Background: Since June 1, residents have been required to use E10 biofuel gasoline, which is a blend of 90% conventional gasoline and 10% bioethanol.
In recent months, Facebook pages run by police units at various levels have published posts that drew strong public backlash.
- Critics argue that the content is inappropriate and harmful to residents, pointing to similar recent controversies involving pages operated by the Hồ Chí Minh City Police, Ô Chợ Dừa Ward Police, and Ba Ngòi Ward Police.
