WASHINGTON - American authorities say a Toronto man has been sentenced to 33 years in prison in what they describe as a “prolific sextortion scheme” that targeted more than 100 children across the United States.

The U.S. Attorney’s Office for the District of Columbia says the sentence comes after 40-year-old Ramanan Pathmanathan pleaded guilty in January to one count each of production of child pornography and coercion and enticement of a minor.
