Facing child pornography charges, Philip Ahr submitted his resignation Monday from the Radnor Township Board of Commissioners.

The resignation of Ahr, who once served as president of the board, was expected to be formally accepted by the board at a meeting Monday night, said acting President Elaine Schaefer.

Ahr, 66, of Bryn Mawr, stepped down as president last month but said he would continue to serve as a commissioner.

He was arrested and charged Oct. 11 with multiple felony counts. Since at least 2013, Ahr allegedly sent and received hundreds of images of child sexual abuse, including some involving infants and toddlers, and animals.

His preliminary hearing was scheduled for Nov. 30. He has been free since posting $100,000 bail.

Ahr was placed on administrative leave from his job as a marketing director at Progressive Business Publications, a Malvern company. For nearly two decades, Ahr mentored at-risk schoolchildren through a company program.

His attorney, Mark P. Much, could not be reached for comment Monday night.
