Two Vietnamese men involved in the fist fight with a foreigner that was captured in a video that went viral last week have been arrested after police investigated the incident, officers said on Tuesday.

Nguyen Du Khanh, 26, and Doan Van Cuong, 29, are being detained by police on charges of “intentionally causing injury to others,” a senior officer from the Hai Ba Trung District police unit confirmed to Tuoi Tre (Youth) newspaper.

Khanh and Cuong were identified as the two men that punched and kicked the foreigner after a road rage accident on Tran Khat Chan Street near the intersection of Vo Thi Sau with Hai Ba Trung on June 23.

One of them was even seen striking the foreign man’s Vietnamese girlfriend on the head.

The foreigner in the video has been identified as an American citizen who preferred to stay anonymous.

He was attacked with a helmet in the face and head, incurring injuries around his eyes and a bloodied nose.

Officers are evaluating the level of injury to the American man and his girlfriend to determine what legal proceedings to take, according to the Hai Ba Trung police.

According to the police file, the victim and his girlfriend were traveling by motorbike when Khanh ran his car over the U.S. man’s foot.

The foreigner tapped on the car’s window, signaling the driver to move his car forward, only for Khanh to jump out and begin beating him in the face and head.

Cuong, a friend of Khanh’s, then arrived from nowhere on his motorbike and rushed to join the assault on the foreigner.

The American man fought the two which resulted in a black eye for Khanh.

The fist fight ended when police officers arrived at the scene.
