WAUKEGAN, Ill. (AP) – A former Illinois state representative who resigned last year amid allegations that he posted online explicit photos of an ex-girlfriend has been indicted on 12 felony counts of disseminating private sexual images.

In a statement issued Wednesday, the Lake County State’s Attorney’s office says the charges against Nick Sauer stem from an investigation that revealed two victims. The office did not elaborate. But last year when the first-term Lake Barrington Republican announced he was resigning after his ex-girlfriend made the allegations, the office said it was taking part in an investigation.

The release does not identify the two victims or say if Sauer’s ex-girlfriend is one of them. It says Sauer is expected to surrender himself on the charges by Thursday morning.
