Anchorage police say they are worried there could be additional victims of a 34-year-old Chugiak teacher accused of sexually abusing a student.

Oly Sugay — who had been teaching at Birchwood Christian School in Chugiak — was arrested and charged with five counts of second-degree sexual abuse of a minor, according to a statement from Anchorage Police Department spokesperson Renee Oistad.

The Oct. 6 arrest comes after school staff contacted APD about “one of their teachers having an inappropriate relationship with a student,” Oistad wrote.

APD said Birchwood Christian staff learned in late September that Sugay had sent “numerous texts to a female student,” Oistad said. The girl’s grandparents discovered an “excessive amount of text messages” on their cell phone bill, which they pay for, according to court records.

When her grandparents called the number she was texting, Sugay identified himself. Police said the student’s age is being withheld for privacy purposes.

“Further investigation revealed that Sugay had been sexually abusing her over the 2015 summer break,” the police spokesperson said. “The abuse ended just prior to school beginning but text messages continued.”

Court records show at least seven sexual encounters occurred between Sugay and the girl beginning in “late June, early July.” Most of the incidents occurred in Sugay’s camper, which was parked in his yard.

The girl told investigators she “knew the relationship was wrong because [Sugay] was married,” court records show.

Sugay was remanded at the Anchorage jail. His bail was set at $7,500 cash-corporate with a third-party stipulation.

Sugay had been teaching an IT class at the school for about a year, said Oistad, adding APD is concerned there could be more victims. Police ask people with additional information to contact Detective Davies at 907-786-8809.
