A substitute teacher from the Peekskill City School District was arrested and charged with promoting and possessing child sexual abuse material, according to the Westchester County district attorney.

Brian Mishk, of Yorktown Heights, was arraigned Friday in the Town of Cortlandt Court and was held on bail.

“This is yet another sad example of a person entrusted with safeguarding our children violating that trust in the worst way,” Westchester County District Attorney Susan Cacace stated. “In this case, Mr. Mishk was allegedly in possession of, and promoting child sexual abuse material. What makes this even more unnerving is that as a school teacher, he was in constant contact with children.”

The 28-year-old was hired as a substitute teacher assigned to Peekskill High School, according to the school district.

Officials with the school district say there is no indication that any PCSD students were involved.

"As always, the safety and security of our students and staff remain paramount at Peekskill Schools. Any student, family and staff who are in need of support should reach out to our administrators or school counseling staff. We will have additional clinical support at the high school available on Monday," said Dr. David Mauricio, superintendent of schools for the district.
