Thunder Bay police have charged a 53-year-old man with sexual assault and possession of child pornography.

Police received a complaint in November of an incident involving the man and a 15-year-old boy.

After an investigation that included the review of video evidence, police executed a search warrant at a home on Wishart Crescent in the city's north side.

Police took the man into custody and seized several computers, cell phones, DVDs and storage devices.

In addition to the sexual assault and child pornography charges, the man also faces charges of sexual exploitation, invitation to sexual touching, breach of probation and breach of a prohibition order.

The police's Cyber Crime Unit is still investigating the items that were seized.

The man appeared in court by video on Sunday morning.  Police have now identified him as Lawrence David Korhonen.
