Federal agents raided the office of a Manhattan dentist, where he is suspected of viewing and distributing child pornography.

John Wolf, 59, a well-known dentist who works on West 15th Street in Chelsea, was charged on Friday with possession of child pornography, ABC 7 reported. Authorities believe underage patients may have been videotaped at his office.

"In recorded conversations with an FBI undercover agent, the defendant admitted that he possessed child pornography and provided the undercover agent with a flash drive containing files depicting child pornography, including videos of children as young as toddlers being raped by adult men," federal prosecutors said in a news release, according to ABC.

Wolf is also accused of exchanging free dental work for crystal meth, then using the drug himself and handing it out to others, NBC New York reported. Wolf is now facing narcotics distribution charges.

The Brooklyn U.S. Attorney’s office revealed even more details on Wolf's alleged escapades in a New York Post report, which included him telling an informant in wiretapped conversations that he "punctured holes in condoms" to infect his sexual partners with HIV. He also reportedly talked of sex parties with animals.

The case, according to the Post, began as just a drug probe before the child porn was uncovered.

“Drug investigations have taken us down dark roads before, but nothing darker than the office practices of Dr. Wolf,” DEA Special Agent James Hunt said in the Post. “What began as a simple drug case quickly rerouted into an investigation into the alleged crimes.”

Wolf is set to appear in federal court in Brooklyn later Friday. 

ABC 7 said that anyone with information about this case, or those that believe they or a family member may have been a victim is asked to call the FBI at 212-384-5000.
