The abuse allegedly took place online between 2019 and 2022, according to the newspaper. The victims are aged 9 to 15 and come from different parts of Finland.
The investigation began in 2022, when the man's phone was examined in connection with another criminal case. At that time, police found thousands of images and videos of unidentified children.
The main crime categories are aggravated sexual exploitation of children, sexual exploitation of children and aggravated dissemination of visual material that depicts children in a sexual manner, Hufvudstadsbladet writes.
The man is said to have confessed to some of the crimes, which allegedly took place via the Snapchat app.
