A Pennsylvania Democrat resigned from his position on Monday night after being charged with child porn and abusing children last month.

Philip Ahr officially resigned from the Radnor Township Board of Commissioners following his resignation as the board’s president in late October, WPVI-TV Philadelphia reported.

The 66-year-old Democrat was criminally charged with possession and dissemination of child porn, abuse of children, and criminal use of communication facility.

District Attorney Jack Whelan said that the crimes Ahr is alleged to have committed were “very disturbing.”

“The ages of these children is particularly disturbing. Anywhere from infants to 2-4 to 3-6, and all in those different categories,” Whelan said.

Whelan’s office released a statement last month that said some of the sensitive material recovered by investigators “depicted sadomasochistic sexual abuse, and children being sexually abused by animals.”

Officials said that Ahr handed in his work iPad on Monday and that they discovered more perverse and illegal images on it — images that he tried to delete.

“It was quite shocking to take a township-issued iPad and to find what we found on there today,” Township Manager Robert Zienkowski told ABC Action News.

“I think it's very disgusting. It’s awful,” Zienkowski continued. “My hope is the prosecutor does everything they possibly can to put this individual away.”
