Police in London, Ont., say they have seized computers containing one of the largest collections of child pornography they have ever seen.
Investigators say the computers and several digital storage devices were found in a home and hold more than 300,000 images and videos.
A 60-year-old man was arrested Wednesday after police noticed several images of child porn had been uploaded online.
Robert Johnson is charged with three counts of distributing child pornography, four counts of possession of child pornography and one count of accessing child pornography.
He is also charged with possession of a controlled substance for the purpose of trafficking.
