Chesco Firefighter Had Child Porn, Sexually Abused Child: Authorities

AVONDALE, PA — A Chester County firefighter has been arrested after federal authorities said he had child pornography and sexually abused a boy he worked with.

Anton Bilski, 25, who was a lieutenant with the Avondale Fire Company as well as a 911 operator, faces numerous charges.

"The Avondale Fire Company is aware of the filing of serious charges against a member who has had his membership revoked and relieved of all responsibilities," the organization said in a statement, noting they are fully cooperating with the continuing investigation into Bilski.

" The department remains committed to providing the highest quality of emergency response and care to the community that we serve," they added.

Bilski has been under investigation since last September, when U.S. Homeland Security received a tip from Europe regarding a suspicious Instagram account.

Officials said Bilski used the account to share and receive hundreds of explicit images of minors.

That activity dates back at least to 2023 and continued through Feb. 2026, authorities said.

Investigators said they also discovered that Bilski contacted a 15-year-old boy for sex through Snapchat in 2021. Police said Bilski claimed to be 18 but was actually 20 at the time.

Authorities are continuing to investigate Bilski and more charges could be forthcoming

He was booked at the Federal Detention Center in Philadelphia. A preliminary hearing will be set in the near future.
