TRENTON -- A Union County man holds the dubious distinction of possessing the largest cache of child pornography ever found by state investigators, according to the head of the New Jersey State Police.

Charles Diggs, 36, was indicted by a state grand jury Thursday after authorities allegedly found him sharing at least a dozen images of child rape on Twitter.

When investigators from the state Internet Crimes Against Children task force tracked the Twitter account to Diggs, they obtained a search warrant and seized his computers, authorities said.

He was arrested in September and a forensic review of his electronic devices found more than 325,000 images and videos of child pornography, according to the state Attorney General's Office.

State Police Superintendent Col. Rick Fuentes said the volume of illicit material was "a record that has helped damage countless children."

Diggs' arrest comes weeks after the conclusion of Operation Statewide, a sweeping investigation that led to 40 arrests in every corner of New Jersey earlier this year.

Elie Honig, the director of the state Division of Criminal Justice, said Friday that the latest case shows "offenders are finding new ways to distribute child pornography, such as Twitter, and they are amassing huge collections of this filth."

Diggs faces charges of second-degree distribution of child pornography and third-degree possession of more than 100 files of child pornography. An appearance in Superior Court in Union County has not yet been scheduled.

Diggs could not be reached and it was not immediately clear whether he had retained an attorney. He is currently free on $125,000 bail.
