Phung Mi Dinh, 43, along with his wife Vu Thi Tho, 44 and their son Vu Mi Po, 19, were going home in Meo Vac District at around 4:50 p.m. when they encountered a stream with rushing water, caused by an erosion, according to the local traffic police department.
As they were trying to walk across the stream, Dinh was stuck in the middle of it, while Tho and her son slipped and were swept away by the water.
Nguyen Manh Tuong, from the traffic police team in Meo Vac District, saw what happened and immediately jumped to the rescue. He held Tho and brought her away from the stream, step by step, before returning to help Dinh and Po.
His heroic act was captured on camera, and the footage later went viral online.
Previously at 3 a.m. Monday, floodwater inundated 25 locations home to over 1,100 houses in Ha Giang. Some areas were submerged up to 2 m underwater. Hundreds of police officers and vehicles were dispatched to rescue people and their properties.
Downpours in Ha Giang since Saturday have caused three deaths due to flash floods and landslides. Over 1,200 houses were invaded by floodwater, while over 220 ha of rice and crops were ruined. Around 18,000 m3 worth of rubbles were eroded down along several routes and highways.
By Tuesday morning, inundations have affected five northern Vietnam localities: Thai Nguyen, Quang Ninh, Hai Phong, Ha Giang and Cao Bang.
In Thai Nguyen, a downpour that lasted two hours on Monday paralyzed vehicles and jammed traffic.
Starting Tuesday, northern Vietnam would enter a period of sunny days, with the highest daytime temperatures at 35 degrees Celsius. Widespread rain is forecast to return on Friday and is expected to last until June 17, mainly in the midlands and mountainous areas.
