“The FBI is receiving an increasing number of reports of adults posing as young girls coercing young boys through social media to produce sexual images and videos and then extorting money from them,” the FBI warning said.

Dozens of boys have reported being “victims of sextortion; mostly for money, although others were reportedly sextorted for additional images,” the agency said in a subsequent news release.

One of those victims was 17-year-old Ryan Last, who lived near San Jose, California. Last died by suicide in February after an extortionist, threatening to post compromising pictures of him on the internet, was demanding more and more money from the teen, his mother, Pauline Stuart, said.
