This picture is a screen capture from an OPP-produced video about the availability of child pornography and child sexual abuse in Ontario. The map shows 8,940 individual Internet Provider addresses that have been identified as download candidates for suspected child pornography in Ontario for the past three months.

A police mapping tool shows hundreds of people in Thunder Bay are sharing images of child sexual abuse.

Toronto Police detective Paul Krawczyk said he put together the map to show where these types of crimes are being committed.

The map, which was part of the OPP’s announcement yesterday about child pornography arrests across Ontario, is littered with dots across the Thunder Bay region.

“I can't really get into the specifics of how we get that data or what we do,” Krawczyk said. “But what I can tell you is it gives us a good idea of what the problem is and what the problem areas are. I think [the map] shows the average everyday person that this isn't ... a problem with ... a small portion of society."

No arrests were made in Thunder Bay as part of this week's province-wide child porn sweep. But police say their investigation is not done.

However, Krawczyk said police don't have the resources to investigate every internet address they see sharing images of child sexual abuse.
