Around 2:30 PM, two teenagers, aged 15 and 18, from Vinh Hung ward, went to Yen So lake in Hoang Mai ward with a younger child. The two boys entered the water to swim, while the younger child remained on the shore, watching their belongings.

After some time, when the two teenagers did not resurface, the younger child ran home to Linh Nam street to alert others.

Authorities immediately launched a search operation, deploying three boats. The first victim was recovered around 8:35 PM, with the second located over an hour later.

Authorities search for the victims. *Viet An*
