Federal prosecutors in New York have charged Canadian fashion mogul Peter Nygard in connection with an investigation into allegations he trafficked and sexually assaulted dozens of girls and women for years.

The nine-count indictment out of the Southern District of New York also charges the 79-year-old Nygard with racketeering and other crimes. He was taken into custody in Canada Monday night, according to press reports in that country.

U.S. federal authorities raided Nygard's Manhattan headquarters earlier this year, a search that came amid claims he trafficked and sexually assaulted dozens of teenage girls and women.
