"He allegedly approached almost 300 young girls on the Internet over the last eight years, in chatrooms, with sexual requests," the public prosecutor said in a statement today.
The man, from the town of Cuijk near the German border, allegedly used a plethora of email accounts and screen names to contact the girls.
He allegedly "persuaded the girls to carry out sexual acts on themselves in front of their webcams," the prosecutor said.
The suspect is accused of having physical sexual contact with 11 girls, three of them at his home.
It is not thought that the man shared the images on the Internet.
The authorities have so far identified 65 of the girls, aged 10 to 17, living throughout the Netherlands.
Dutch media reported that the parents of a 16-year-old girl had gone to police around nine months ago because she was having a relationship with the suspect.
A senior officer admitted to Dutch media that police had committed a "procedural error".
Police are trying to identify the other girls in the images.
