Police have arrested more than 35-hundred people over the past year in a nationwide crackdown on online sex crimes, including deepfake offenses.

According to the National Police Agency on Sunday, police apprehended a total of three-thousand-557 people in connection with online sex crime allegations between November 2024 and October this year, detaining 221 of them.

The number of arrests marks a 47-point-eight percent increase from the previous year. 

Crimes involving deepfake technology accounted for the highest percentage of the total, or over one-thousand-500 cases.

The next most common cases involved videos depicting the sexual exploitation of children or adolescents, illegally filmed materials, and other sexually explicit videos.

Teenagers made up the highest percentage of the accused individuals, with over 17-hundred teens caught in the crackdown.

People in their 20s were next, numbering about one-thousand-220, followed by people in their 30s and 40s.

Authorities said the high proportion of teens and young adults reflects heavy use of digital media within those age groups.
