The FBI and NYPD detectives raided the Manhattan headquarters of fashion executive Peter Nygard on Tuesday morning in connection with an ongoing sex-trafficking investigation, according to the New York Times, citing two law enforcement officials who spoke on condition of anonymity.

The 78-year-old Nygard has been under investigation for at least five months by a joint child-exploitation task force overseen by the Manhattan US attorney's office. According to the report, at least four women have accused Nygard in a lawsuit of sexually assaulting them when they were 14 and 15.
