A Montreal police news release said they have reason to believe Krupp committed crimes of a sexual nature against minors between 1970 and 1976, and are asking for the public’s help in identifying more victims.
The 68-year-old man is already facing charges following his November arrest for allegedly stalking schoolchildren in Kirkland, on Montreal’s West Island.
Krupp had previously pleaded guilty to charges of possession and distribution of child pornography after a previous arrest in 2000. He was sentenced to 18 months to be served in the community.
When contacted by CBC previously, Krupp said he got a pardon.
People who may have been victims of Krupp’s, or people with more information about him, are asked to call Montreal police at 514-280-2299.
