The FBI and New York State police are investigating what the Port Byron School District superintendent said are alarming and illegal internet posts made by students.

Neil O'Brien alerted parents in a newsletter on Friday, saying the probe has to do with posting nude photos.

"I leave you with two thoughts: One is the fact I have to write in generalities to protect student privacy, and not share too much,” the letter said. “The second is that both the volume and the subject matter of these stories would make you cringe and cry. There are far too many of them, and some are just heartbreaking. Having people arrested might mean that someone pays a price, but for the victims, that cost is way too high."

The investigation is ongoing.
