The St. Paul man who allegedly posed as an acting teacher in order to lure young girls was charged in a third case after police discovered video of him molesting a child in a public library.

Nicholas C. Barghini, 31, was charged last week in Ramsey County District Court with one count of felony second-degree criminal sexual conduct. He was charged this past summer with two counts of fifth-degree criminal sexual conduct in two separate cases at St. Paul's Riverview Library involving an 8-year-old and 10-year-old girl.

The newest case involves his alleged actions at the city's Merriam Park Library with a girl who was either 10 or 11 years old.

According to the criminal complaint: police investigating the other two cases recovered video from Barghini's hard drive that showed him instructing the girl in the Merriam Park incident to recite a monologue. The girl was participating in an acting class he hosted on July 15.

The girl was lying on her stomach across a row of wooden chairs with her feet in Barghini's lap. No one else was in the room. Barghini allegedly tickled her feet while masturbating, and then touched and rubbed his genitals on the bottom of her foot and toes, the complaint said.

The other alleged incidents, at the Riverview Library, occurred on June 17 and July 29, and involved similar behavior, although they did not allege any contact with Barghini's genitals, court documents said.

Barghini's online résumé notes that he has volunteered at the St. Paul Jewish Community Center as a camp counselor and coached sports at Linwood Monroe Arts Plus school in St. Paul.

Barghini has hearings in all three cases in December.
