A man from Abbotsford, B.C., is facing child sex assault and pornography charges after allegedly selling a laptop containing child porn.

Jonathan Grunwald, 52, has been charged with sexual assault of a person under 16 years of age, sexual interference, invitation to sexual touching, making child pornography and possession of child pornography.

The police investigation was launched after someone who bought the laptop from the Craigslist website found disturbing images on the computer and brought it to police.

Police checked the laptop and found images of child porn, some of which they allege was made by Grunwald. So far, one child victim has been identified, and the investigation is continuing, Abbotsford police said.

The child is safe, and support has been established for the child's family, a police statement said.

Const. Ian MacDonald said the evidence uncovered was very disturbing.

"We don't want to do anything to identify the victim, but I can say this much: I believe the details of this investigation would shock any police officer or any community member."

Grunwald had no previous record, said MacDonald, but that's common in these sorts of cases.

"There seems to be a strong correlation between people having no prior criminal history, and then ultimately out of the blue being charged with child porn offences."

Anyone with information about this investigation is asked to contact the Abbotsford Police Department at 604-859-5225, text 222973 (abbypd) or call Crime Stoppers at 1-800-222-8477.
