Jeju: police refer a middle-school student over secretly filming teachers and making sexual deepfake composites; teachers dispute victim count and legal aid

Jeju Dongbu police announced on 23 September 2026 that a student at a middle school on Jeju had been referred to prosecutors without detention on 17 September for violating the Sexual Violence Punishment Act (filming with a camera or similar device). The student's phone was voluntarily submitted by his guardians and forensically examined; the examination found footage relating to some teachers and some sexual composites, and the student admitted the conduct. News1 reported that the student was booked for filming a teacher's body with his phone during a school field trip around mid-July 2026, that the offending had continued for several months with multiple victims, and that police found no indication the composites had been distributed. Police told Seoul Shinmun there were more victim teachers than the one first reported but withheld the number to avoid secondary harm, and that no student at the school was a victim; the Jeju teachers' union questioned whether the full scope of harm had been established. According to the union, two months on the victim teachers were receiving hospital treatment and counselling while teaching daily, gave police statements on 14 September without a lawyer, attended the regional teachers' rights protection committee on 17 September without institutional support, wrote the criminal complaint themselves, and were offered 3.3 million won in legal fees for all of them together, payable after the case ends; two requests to meet the superintendent were not accepted. On 29 September one of the victim teachers gave a press interview at the Jeju Teachers' Union office. She said that early in the investigation she had seen on the student's phone material showing other teachers and current students, had made a list of the people and types of harm, and that the material shown to her at the police victim examination was considerably less than what she had seen; Yonhap-chain outlets quote her as saying the students she recognised numbered 10 to 20 and that a graduate had suffered worse deepfakes. She said investigators asked the school only to identify the perpetrator and never requested material to identify the students in the footage, and that the school sent parents a letter premised on there being no student victims. Police replied that phone forensics had been thorough, that every act beyond social norms had been identified and proven, and that one student victim had been confirmed, a student at a different school. The teachers were notified on 22 September that the case had gone to the prosecution and on 24 September that it had been sent to the court's juvenile division as a juvenile protection case, before they had submitted further evidence and a victim opinion. The teacher said the original complaint had also asked police to examine whether physical contact in 2025 was forcible molestation and whether repeated approaching and waiting in 2026 was stalking, and Halla Ilbo reports that such conduct is said to date from 2025. Yonhap-chain reports describe the charged victims as five teachers. The same day the education office briefed on legal-aid rules (up to 6.6 million won per instance when a teacher is sued, 3.3 million won per case when a teacher files a complaint; office lawyers cannot act as a teacher's private counsel), said it had linked the teachers to the national Digital Sexual Crime Victim Support Center, announced an integrated support system through a hotline, and its section head said the office was sorry that early support had not been felt. The KTU Jeju branch (28 September) and the Jeju Teachers' Union (14 and 29 September) demand a victim-support system, per-teacher legal fees paid in advance and a dedicated support team. On 6 October 2026 Seogwipo Broadcasting reported, citing people in education and a tipster, that the education authority had finally rejected the victim teachers' application for lawyer fees for an additional criminal complaint, saying in a written opinion that with a police investigation already under way a further complaint could hardly stop or prevent the infringement of their teaching, so the support requirements were not met; critics contrast this with full legal-cost support in earlier sexual-offence cases.

Nagoya, Japan: a former elementary-school teacher was sentenced on 4 June 2026 to three and a half years, including for possessing generative-AI nude images made from school photos of two girls; reported as Japan's first conviction applying the child-pornography law to AI deepfakes

On 4 June 2026 the Nagoya District Court sentenced a 35-year-old former Nagoya municipal elementary-school teacher to three years and six months in prison. Prosecutors had sought six years. He was one of seven current and former teachers from five prefectures charged over a group chat in which members shared secretly filmed images of girls. His offences included secret filming and sharing, and, under the child-pornography law, possessing two generative-AI images showing two real girls apparently naked. According to the police and the judgment summary, he sent photos of the girls from the school where he taught to another member of the group, who made the images on an AI image-editing website. The teacher kept them on his phone, and one was shared in the chat. The judge found the images realistic enough to be mistaken for photographs of the girls. Jiji called it the first case in Japan applying the law to possession of AI-generated sexual deepfakes, and Kyodo called it apparently the first such court finding. A lawyer and a former judge argue the law was stretched.

Incheon high-school student jailed for AI deepfake nude composites of his teachers posted online; a civil court later orders him to pay one teacher damages

In July 2024 a high-school student in Incheon, South Korea, composited the faces of two female teachers at his school and of others, including an academy senior and an instructor, onto nude photos and posted them on social media, according to the charges as reported by Yonhap, the Hankyoreh, the JoongAng Ilbo and the Kyunghyang Shinmun, which describe the technique as AI-based deepfake technology. He had also secretly photographed teachers in class. He was expelled after a teachers' rights committee hearing. On 27 August 2025 the Incheon District Court gave him an indeterminate prison term of one year to one year six months and took him into custody; the court said that as a result the victimised teacher had left teaching and had not returned. On 19 December 2025, after he had turned adult, the appeal division raised the sentence to three years, calling the offence close to 'character assassination' and the teachers' mental shock considerable; OBS reports the sentence is final. On 21 October 2026, according to the Incheon Teachers' Union, a civil judge at the Incheon District Court ordered him, now 20, to pay one teacher 17.7 million won of the roughly 72 million won she claimed.
