Various group chats and Facebook and Reddit posts are being passed around claiming a modus operandi of Davao police allegedly planting drugs into vehicles. The post is FAKE, and is an old hoax dating as far back as 2018.
MindaNews is fact-checking this claim as there are pages with many followers as well as misinformed users spreading the rumor online.
The text usually goes as follows:

Copy pasting some paragraphs and texts, MindaNews found several pages, including those with tens of thousands of followers, sharing the post or creating some themselves.

MindaNews found some Reddit users already fact-checking posts by others.
One such fact-check led to a post by Indian Fact-Checking site Boom Live which posted a fact-check of a post with similar content in 2018. The Boom Live fact-check is eight years old, and also included posts allegedly from Filipino social media pages, such as The Daily Sentry.
The Daily Sentry Posts have since been deleted.
Boom Live, in the 2018 fact-check, identified the circulating text message with similar elements to the currently viral text.
In both chain messages, there are checkpoints, mentions of right turns, the keywords “ok ok u may go” and “guess what,” advice for others not to open their trunks, among others.

In a statement sent to MindaNews, Davao City Police Office spokesperson PCpt Hazel Caballero Tuazon denied the incident and invited possible victims to file a blotter.
The spokesperson added that all DCPO checkpoints follow a plain-view protocol during checkpoints, and that trunks are not required to be opened.
The posts, the DCPO added, did not include evidence.
Tuazon said that victims of police abuse may file a complaint or blotter so that erring police officers can be reprimanded.
Hoaxes are easily passed on from one user to another since forward chains, or chat/text messages forwarded from one user to another, cannot be attributed immediately to its original source.
As with all our other reports, MindaNews welcomes leads or suggestions from the public to potential fact-check stories.
