Previously, the Economic Police Department - Hanoi City Police had just verified, investigated, and arrested 3 subjects related to a group that illegally discharged nearly 50m3 of waste into the To Lich River, causing environmental pollution and public outrage.
Specifically, at around 3:00 a.m. on September 5, 2025, in the area of the To Lich River embankment, the section opposite 584 Lang Street (Lang Ward, Hanoi), the Yen Xa Wastewater Treatment System Project Management Board discovered a stream of waste suspected to be phosphorus fertilizer discharged directly into the manhole, then flowing straight into the river.
It is estimated that the amount of waste is up to about 50m3, causing a strong stench and serious pollution in a large area.
Upon receiving the report, under the direct direction of the City Police Department, Team 3 - Economic Police Department - Hanoi City Police quickly took action.
Through the urgent verification and review process, the police determined that the white tanker truck with license plate 30L-573.96 recorded by a security camera belonging to Hanoi Urban Drainage Environmental Sanitation Company Limited illegally discharged waste into the To Lich River through the manhole system.
This is a company founded by Nguyen Khac Dao (born in 1982) and Chu Thi Vang (born in 1983). During the investigation, the subjects confessed that Dao and his wife's company did not have a waste treatment license and did not sign with any legal treatment unit. Therefore, after sucking the phosphorus tank, Dao directed the driver to transport it to unregulated locations for dumping.
The behavior of the subjects resulted in broken pipes in the manhole, untreated waste overflowing directly into the To Lich River, causing serious pollution and a strong stench.
