FAIRFIELD — A man swept up in an online predator sting last October faces an additional charge.

Vincent Ambrosio, 20, of Wappinger Falls, N.Y., was charged on a warrant last Friday with third-degree possession of child pornography.

Ambrosio was one of 10 men charged in a sting last Oct. 5 at a house in Fairfield. The sting, set up by television personality Chris Hansen, Fairfield police and State’s Attorney John Smriga, arranged for Fairfield University theater students to pose online as teen boys and girls. When the suspects showed up at the house to have sex with the teenagers, they were arrested, and the incidents were video recorded for a planned television program.

Police later obtained a search-and-seizure warrant for two cellphones in Ambrosio’s possession. Based on the images that were found, according to the report, the child pornography warrant was secured.

Ambrosio is scheduled to appear Monday at state Superior Court in Bridgeport.
