HONOLULU (AP) — A Hawaii public school teacher is being held without bail and charged with distributing child pornography, which U.S. prosecutors said included videos of him having sex with a 13-year-old student.

According to a criminal complaint, Alden Bunag, 33, worked as a substitute teacher at multiple schools and sent videos of himself having sex with a boy during school lunch breaks in 2019 to a teacher in Philadelphia.

FBI agents arrested Bunag last week at an Oahu high school where he was working as a summer school teacher.

Bunag told agents he had sex multiple times with a then-13-year-old boy who was his student and sent a video recording to the Philadelphia teacher and others, the complaint said.

“I have no comment at this time,” Jacquelyn Esser, Bunag’s federal defender, said in an email Wednesday.

The Hawaii Department of Education didn’t immediately respond to a request for comment.

Prosecutors asked that any other possible victims contact the FBI in Honolulu.
