A 49-year-old man is facing child pornography charges following an investigation that began in May.

Police say an OPP officer began what they're calling a "proactive investigation" into the online chat website ChatStep.

Investigators found an Ottawa-based IP address linked to uploads of child pornography.

Police executed a warrant Thursday in Ottawa and made an arrest in the west end.

Beau Breaky is facing two counts of possession of child pornography and four counts of making it available. He'll be in court Friday.

Police say more charges are expected, once they examine the digital devices they seized at the scene.
