A Sudbury man is looking at 22 counts of various child pornography offenses after police seized computers in a raid.  Police became aware of downloading activity involving child pornography beginning last September.  After monitoring the activity for a few months, they raided the man’s home and seized several computers in late December.  An examination of those computers gave police enough evidence to arrest the man on Tuesday.  The 22-year-old is charged with eight counts of accessing child porn.  He’s also facing seven counts each of making available child pornography and possession of child pornography.
