Investigators searched his home after receiving a cybertip from the National Center for Missing and Exploited Children. The center said a person using a vulgar Yahoo ID had been uploading images of prepubescent boys. The account was traced back to Devine.
"Mr. Devine admitted to the possession of child pornography at that time," Delaware County District Attorney G. Michael Green said of Wednesday's search.
Green said his office had not received reports that Devine had sexually abused children, but the investigation is ongoing.
"We're also reaching out to any parent whose child may have had any kind of contact with Mr. Devine to touch base with us," he said.
Devine, who has worked in the West Chester Area School District since December 2008, was suspended from his teaching job following yesterday's arrest. District Superintendent Jim Scanlon said Devine had cleared state and federal background checks before he was hired.
"No infractions were reported in these clearances, and we have had no reports of any improper conduct by Mr. Devine during his employment with the district," Scanlon said in a statement. "In addition, the district's filtering software does not allow any access to pornographic Web sites from any of our school locations."
Green spokeswoman Erica Parham said it was unknown yesterday whether any of the pornographic images on Devine's personal computers were of kids who attended his camp or classes.
Devine did not immediately post bail, set at 10 percent of $250,000. If he does come up with the money, he must undergo a psychological evaluation before his release and is barred from having contact with minors.
