Tel Aviv police arrested a 21-year-old from the south, with no criminal record, on suspicion of setting up telegram groups, some for a fee, and showing sexually explicit images of hundreds of Israelis, including dozens of minors, some of them well-known.
In recent months, police have been able to track down a number of telegram groups of a sexual nature.
This morning (Monday) the investigation became public, when the suspect was arrested.
The telegram groups had an economic aspect - those who wanted to join the group would pay money through paid apps.
The victims of the groups are hundreds of women, dozens of minors, whose revealing photos have been circulated.
The police emphasize that this is a serious affair, in which they conducted covert network surveillance and gathering evidence against the "source of trade and distribution", while using advanced technological means, including infiltrating the telegram widget, in a way that overcomes network anonymity and security restrictions.
