Male students and trainee teachers at a prestigious school in Chorakhe Bua have appealed to the 'Sai Mai Must Survive' group, alleging that an LGBTQ social studies teacher sexually harassed them by fondling their thighs and genitals. Nearly 30 students are reported to be victims.
At 10:30 a.m. on 12 July 2026, at the coordination center of the 'Sai Mai Must Survive' page on Wat Ko Road, Sai Mai district, Bangkok,
Mr. A (alias), 18, Mr. B (alias), 18, both Grade 12 students at a well-known secondary school in Chorakhe Bua, and Ms. C (alias), 45, mother of a male trainee teacher at the same school, came to seek assistance from Mr. Ekaphop Luengprasert, founder of the 'Sai Mai Must Survive' page, and Mr. Niran Keaw, co-founder. They reported that the two students, nearly 30 male peers, and a male trainee teacher were sexually molested by Mr. Rungruangsap (surname withheld), about 45 years old, an LGBTQ social studies teacher, who allegedly touched their genitals. The trainee teacher was also a victim.
Mr. A stated he was first abused in early June 2024 while in Grade 10. Sitting at the front desk, the teacher touched his thigh and tried to reach inside his pants to grab his genitals. He pushed the teacher’s hand away and said he was uncomfortable. The teacher then repeatedly tried to molest him both inside and outside the classroom from Grade 10 to Grade 12, even calling him to meet privately. When he refused, the teacher confronted him during morning line-ups, asking why he ignored the calls. Feeling distressed, he had to move his desk to the back. Over the past 2-3 years, when unable to abuse him, the teacher targeted his friends. In his class, 4-5 students were affected.
Mr. B said that on days assignments were submitted, the teacher would call him alone to a closed room and abuse him similarly to Mr. A—touching his thigh and fondling his genitals, then asking intrusive questions like whether he masturbated, how it felt, or if he had sexual relations with men. He was first abused in early November 2025 and has been targeted repeatedly since.
Regarding why they did not report the abuse earlier, they said they did not want conflicts with teachers. They discussed among male peers in their grade and others and learned nearly 30 students had suffered similar abuse, none consenting. The issue surfaced publicly recently after related authorities began investigations, and the teacher was transferred to the Bangkok Secondary Education Service Area Office 2 on Lat Phrao Road, Sam Sen Nok subdistrict, Huai Khwang district, Bangkok, in early July. The teacher was previously transferred from a school in Min Buri about four years ago due to similar misconduct.
Recently, on the evening of 7 July, Mr. A and Mr. B encountered the teacher trying to follow them by car, prompting safety concerns. The two filed a police complaint for sexual molestation against the social studies teacher on 10 July.
The trainee teacher’s mother said her 21-year-old son, a fourth-year student at a university in Bangkok, was doing his social studies teaching practicum at the school. The accused teacher was his mentor and evaluator. The trainee suffered psychological distress and depression during the less than two months of his recent practicum but endured it as graduation was approaching.
Mr. Ekaphop said they will continue liaising with the abused male students and their parents to follow up on the case at Khok Kram Police Station, urging authorities to expedite legal proceedings.
