Police in Bac Lieu Province have arrested a primary school principal for allegedly molesting two girls studying in his school.
An officer said Nguyen Van Toan, 46, would be held for three months.
Police said there is evidence of Toan molesting seven students multiple times.
They looked into the case after the parents of two victims, both 11, lodged complaints.
One of the mothers said her daughter, identified only as T., was molested on April 25.
A video shot by her classmate, also a victim, shows Toan pull T. into the school’s toilet and hold her tightly. She tries to run but he pulls her back and touches her inappropriately, it shows.
T.’s mother said the girl has become affected. “She seems worried all the time and stays away from everyone.”
The mother said many people from Toan’s family have come to her house to apologize and offer compensation, but her family turned it down.
“We cannot tolerate his act. We cannot let it go.”
In Vietnam, more than 8,200 cases of child abuse came to light between 2011 and 2015, including 5,300 cases of sexual abuse, according to official figures released last March.
In most cases the perpetrators were people having authority over the children, like teachers, school security guards and even fathers.
