A 52-year-old man from Thunder Bay faces two child pornography charges, after a tip came into police from the National Child Exploitation Coordination Centre.
Police said they were advised that child pornography images were uploaded to Twitter.
Jeffrey Frederick Miro turned himself into police on Tuesday, and was taken into custody. He made a court appearance Wednesday on charges of possession of child pornography and making it available.
Police report the charges stem from an investigation that started on April 4.
Based on that initial investigation, police later searched a home on Chilton Avenue and seized a computer, a tablet, two smart phones and two flash drives.
Police said they found child pornography on the devices.
