Eight inmates of South Carolina prisons – three of whom are Bloods gang members – have been charged in a “sextortion ring” that made them at least $144,000 through their solicitation of hush money from victims, federal officials say.

Federal prosecutors say the eight inmates targeted military men through dating apps by using cell phones with internet connections that had been smuggled into the prisons.

The inmates pretended to be women, and sent nude photos to the victims, prosecutors say. They would then pretend to be the father of an underage girl and threaten to call the police and accuse the victims of soliciting photos from minors, court filings say.

An indictment filed in Florence’s federal court accuses the eight men of accepting more than 70 “fraudulent money transfers” from the victims, Columbia’s The State newspaper reported Monday.

At least twelve other people have been charged, and several others have pleaded guilty to their involvement in the scheme that scammed more than 400 members of the military, prosecutors say. In total, the scheme netted about $560,000 for the eight inmates and their accomplices outside the prison.
