Chennai, Nov 8 - A Dutch national living in the Tamil Nadu capital for the past three decades has been arrested for uploading child pornographic pictures on the internet from his house, police said Sunday.

The cyber crime police cell Saturday arrested 56-year-old W. Williams, who claims to be a social activist, under the Information Technology Act 2008 on an alert from the Interpol.

A German-based child protection centre had earlier alerted the Interpol about the uploading of pornographic pictures from here on the site.

According to the Chennai cyber crime police, the source of pictures was being investigated. The police will also analyse the data stored in the seized laptops, pen drives belonging to Williams.

Police say Williams had jumped bail after being arrested earlier for alleged child abuse. A case against him is pending in the Mahabalipuram police station near here.
