On December 29, the People's Committee of Chieng Hac commune, Son La province received information that a wild monkey attacked people in the Coc Lac village production area. The victim is Mr. Hoang Van Toi, who was attacked by a monkey while working in the fields and had to be hospitalized for treatment.

According to initial verification, the monkey appeared in this area from the beginning of December 2025, showing signs of bewilderment and becoming increasingly aggressive.
Previously, on December 24 and 26, the monkey also attacked Mr. Hoang Van Pao and Mr. Hoang Van Phong, both from Coc Lac village, causing minor scratches.
Mr. Cao Xuan Dung, Chairman of the Commune People's Committee, informed that immediately after the incident occurred, leaders of Chieng Hac Commune People's Committee coordinated with local forest rangers to go to the scene to verify, visit, and encourage the victims. At the same time, establish a working group to inspect the area where monkeys regularly appear, and develop an early handling plan to ensure safety for people.

The commune has also directed villages to propagate to people to limit going alone in forest and field areas; not to tease, feed monkeys or approach closely; when discovering wild monkeys, promptly report to local authorities.
