'Slut-shaming' on Instagram could lead to charges for Swedish teens GOTHENBURG, Sweden, April 10 (UPI) -- Two teenage girls in Sweden may face criminal charges for setting up a "slut-shaming" account on Instagram, authorities in Gothenburg say. Annika Boman, a prosecutor, told Svenska Dagbladet the girls would be charged with aggravated defamation. Charges will likely be formally filed at the end of April, but it may also take longer. New information may emerge in the investigation," she said. The account set off a riot outside Plusgynmasiet high school in Gothenburg in December, The Local.se reported.

Boman said many students have provided her with screen shots of material they say defamed them.
