PROVIDENCE, R.I. (AP) — A 20-year-old Providence man has been arrested for the third time since 2012 on child pornography charges.

Gregory Lombardi Jr. was ordered held without bail Tuesday after being charged with two counts of possessing and two counts of transferring child pornography. Prosecutors say he violated the terms of a 2012 bail stemming from another child pornography arrest.

They say he also had been arrested in February on charges of possession of child pornography and indecent solicitation of a minor.

Prosecutors say the charges resulted from investigations by the National Center for Missing and Exploited Children and the Department of Homeland Security into images that had been uploaded onto social media web sites.
