Fort Lauderdale, Fla., law firm leader Scott Rothstein would piggyback on actual lawsuits, including one tawdry case his firm was handling, to solicit investors in an alleged Ponzi scheme, according to a lawsuit by investors claiming more than $100 million in losses.

The Broward Circuit Court case filed Friday alleges Rothstein told investors he was handling confidential settlements with billionaire financier and convicted sex offender Jeffrey Epstein, who was accused of engaging in sexual activities with underage girls.
