A female teacher repeatedly committed sex offences against one of her students, who was a 15-year-old girl.

On Oct 5, the 35-year-old woman, who engaged in sexual encounters with the minor from Oct 13 to Nov 21, 2023, was sentenced to nine years’ jail.

She had pleaded guilty to two counts of performing an indecent act on the minor and a sexual penetration charge.

SINGAPORE - A married female teacher committed sex offences against one of her students, who was a 15-year-old girl, at a karaoke and bistro, their school and on a public bus.

She had engaged in sexual encounters with the victim from Oct 13 to Nov 21, 2023, and pleaded guilty to two counts of performing an indecent act on the minor and a sexual penetration charge.

Seven other charges, including one count of exchanging at least three sexually explicit audio recordings, were considered during sentencing.

Details about the woman and the school cannot be disclosed owing to a gag order to protect the victim’s identity.

Court documents stated the Secondary 3 student had a history of family problems and struggled with various mental health conditions.

Child Protection Services (CPS) had also intervened due to her parents’ use of harsh physical punishment on her.

Around the time of the woman’s offences, the girl was warded at the Institute of Mental Health (IMH) from Oct 27 to Nov 3, 2023, due to her self-harm behaviour and having suicidal thoughts.

Deputy public prosecutors Selene Yap and Yeo Kee Hwan stated in court documents the offender became the victim’s teacher for one of her subjects in 2023.

In April that year, the girl approached the woman for support and advice on her home situation, texting her frequently to share about her struggles.

They grew closer and entered into what the victim described as a “situationship” and engaged in a series of sexual encounters.

They also exchanged at least three sexually explicit audio recordings.

At around 1pm on Oct 13, 2023, the pair went to a room at a karaoke and bistro where they engaged in their first sexual encounter.

That weekend, the woman told the victim they had to stop this .

The girl agreed, and they decided to meet after she finished one of her examinations.

But on Oct 16, 2023, they were at school at around noon, when they entered a staff toilet, which was a single cubicle, and engaged in sexual acts .

On Nov 7 that year, they boarded a double-decker public bus and the woman performed a sexual act on the girl at the upper deck.

Their final encounter took place in a room at a “chill out” facility on Nov 21, 2023, where the girl sexually penetrated the woman.

The DPPs said the pair fell out over undisclosed reasons.

On Jan 16, 2024, the girl told her CPS-appointed safety adult, who was also the year head at the school, that the teacher had sexually assaulted her.

The matter was referred to the vice-principal who took the girl to a police station the next day to lodge a report. The teacher was arrested on Jan 18, 2024.

The girl went to an IMH outpatient clinic and a doctor’s report stated she had talked about breaking down in school as it reminded her of the sexual acts . She was then diagnosed with adjustment disorder.

On Aug 26, 2024, she underwent an evaluation at the Child Guidance Clinic, and said she had been feeling sad, numb, and angry since the offences.

Court documents stated she became easily startled, had difficulty focussing during lessons, had difficulty trusting adults, and her academic performance deteriorated.

A second doctor stated her symptoms were consistent with a diagnosis of post traumatic stress disorder.

The offender was represented by lawyer Kalaithasan Karuppaya, and her husband had provided a testimonial, believing she is capable of genuine rehabilitation.

In sentencing her, District Judge Paul Chan said: “I have read the many testimonials tendered to you, and it’s clear you have many redeeming qualities.

“Upon your release, apply these qualities for the benefit of your family and wider community.”

The Straits Times has contacted the Ministry of Education to find out more about the woman’s current employment status.

一名女教师多次对她的一名学生实施性侵犯，该学生是一名 15 岁的女孩。

10 月 5 日，一名 35 岁的女子因在 2023 年 10 月 13 日至 11 月 21 日期间与未成年人发生性关系而被判处九年监禁。

她承认犯有两项对未成年人实施猥亵行为的罪名和一项性侵犯罪名。

新加坡——一名已婚女教师在卡拉OK和餐馆、学校以及公共汽车上对她的一名15岁女学生实施了性侵犯。

2023年10月13日至11月21日期间，她与受害者发生性接触，并对两项对未成年人实施猥亵行为的指控和一项性侵犯指控认罪。

量刑时还考虑了其​​他七项指控，其中包括一项交换至少三段露骨性音频录音的指控。

由于有禁言令保护受害者的身份，有关该女子和学校的详细信息无法透露。

法庭文件显示，这名中三学生有家庭问题史，并患有多种精神健康问题。

由于她的父母对她进行严厉的体罚，儿童保护服务机构（CPS）也介入了此事。

在女子犯罪前后，这名女孩因自残行为和有自杀念头，于 2023 年 10 月 27 日至 11 月 3 日在心理卫生学院 (IMH) 接受治疗。

副检察官叶思琳和杨基焕在法庭文件中指出，被告于 2023 年成为受害者的其中一门科目的老师。

同年四月，这名女孩向这位女士寻求帮助和建议，倾诉自己的家庭困境，并经常给她发短信。

他们关系日益亲密，进入了受害者所描述的“暧昧关系”，并发生了一系列性行为。

他们还交换了至少三段露骨的性爱录音。

2023年10月13日下午1点左右，两人来到一家卡拉OK兼小酒馆的包间，在那里发生了他们的第一次性行为。

那个周末，这名女子告诉受害者，他们必须停止这种行为。

女孩同意了，他们决定在她考完一场考试后见面。

但在 2023 年 10 月 16 日，大约中午时分，他们在学校里进入了一个教职工厕所（只有一个隔间），并发生了性行为。

同年11月7日，她们登上了一辆双层公共汽车，该女子在上层对女孩实施了性行为。

她们的最后一次见面发生在 2023 年 11 月 21 日，地点是“放松”场所的一个房间，女孩对女子进行了性侵犯。

检方表示，两人因不明原因闹翻。

2024 年 1 月 16 日，这名女孩告诉 CPS 指定的安全成年人（同时也是学校的年级主任），老师性侵犯了她。

此事已移交副校长处理，副校长第二天带女孩去警察局报案。该教师于2024年1月18日被捕。

女孩前往心理健康研究所（IMH）门诊就诊，医生报告显示，她曾谈到在学校情绪崩溃，因为学校会让她想起性侵事件。随后，她被诊断为适应障碍。

2024 年 8 月 26 日，她在儿童指导诊所接受了评估，并表示自犯罪行为发生以来，她一直感到悲伤、麻木和愤怒。

法庭文件显示，她变得容易受到惊吓，上课时难以集中注意力，难以信任成年人，学习成绩也下降了。

第二位医生表示，她的症状符合创伤后应激障碍的诊断标准。

被告的代理律师是卡莱塔桑·卡鲁帕亚，她的丈夫提供了证词，相信她有能力真正改过自新。

在宣判时，地方法官保罗·陈说：“我阅读了提交给你的许多证词，很明显你有很多值得称道的品质。

“获释后，请将这些品质用于造福您的家人和更广泛的社区。”
