A man who was taking illegal photos of a woman at a subway station in Seoul, South Korea, was arrested by police at the scene with the help of a citizen. On the 9th, the National Police Agency posted a video on its official YouTube channel titled "I grabbed a citizen by the collar.
The video, titled "Subway Voyeur Bitten," was released. The video shows a man wearing black clothes and a mask following a woman up the stairs at a subway station in Seoul.
The man followed the woman to the stairs leading to the exit and tried to take pictures illegally with his mobile phone at an angle. A citizen who was watching closely caught the man taking pictures illegally.

The man, who had denied committing the crime, admitted to the police after persistent questioning, saying he had taken several photos. When the police searched the man's mobile phone, they found hundreds of illegally taken photos.
