SINGAPORE: A former army captain was introduced to a 15-year-old student by his ex-partner, a cook in the navy, and the trio engaged in sex acts at a multi-storey car park .

Thereafter, the captain stayed in contact with the minor and met him for more sexual acts, filming them for his "personal collection".

Chaw Chia Jun, a 41-year-old Singaporean, was sentenced to 17 months' jail on Tuesday (Oct 20).

He pleaded guilty to three charges of sexual penetration of a minor, causing a minor to perform sexual penetration and producing child abuse material.

The court heard that Chaw was 39 at the time of the offences in 2024 and held the rank of captain in the Singapore Army.

His co-accused, 26-year-old Owen Toh Wei Song, was a cook with the Republic of Singapore Navy.

Chaw and Toh had been in a relationship between 2021 and 2022 and remained in contact after breaking up.

Around April 2024, the victim, a 15-year-old student in Secondary 4, conducted an internet search for ways to make friends online.

He came to an online forum for mature Singaporean gay men and found Toh's profile.

He initiated contact with Toh and they began discussing sexual topics. Toh said he was not experienced in a certain niche area but that Chaw was.

The victim agreed to meet Chaw, with Toh lying to the victim that Chaw was 32.

Sometime before Jun 5, 2024, Chaw picked Toh up before driving to fetch the victim.

They then went to a multi-storey car park in Punggol where Chaw asked the victim to strip.

Toh then engaged in sex acts with the victim, with Chaw filming.

Chaw performed a sex act on the victim and the trio later got dressed and left.

After the incident, Chaw sent a copy of the video to Toh at his request.

CHAW MET VICTIM AGAIN

Chaw later met the victim on his own on several occasions.

One such encounter took place at a shopping mall on Jun 5, 2024, where they entered a toilet for the disabled and engaged in sexual acts.

Chaw took two videos of the acts, one of which captured the victim's face.

Chaw kept the videos on his phone. He later said he made and kept recordings of his sexual activities with others in what he described as his "personal collection".

The victim's mother and sisters grew concerned about his behaviour as well as the gifts he had been receiving from a man, which turned out to be Chaw.

When confronted, the victim told his mother and sisters what had happened before lodging a police report on Oct 23, 2024.

Toh was sentenced to 12 months' jail last month.

SENTENCING ARGUMENTS

Deputy Public Prosecutor Maximilian Chew sought 17 to 21-and-a-half months' jail for Chaw, noting that the offence of sexual penetration of a minor exists to protect a class of vulnerable people - minors under 16.

Defence lawyer Mark Yeo said his sentencing position was not far from the prosecutor's.

This is because Toh was the one who introduced Chaw to the victim and was the more active party in the car park incident.

The prosecution had argued that the car park incident involved "gratuitous degradation" as the victim was naked in the open.

Mr Yeo said the location had been selected "in discussion with the victim", and it was Toh who asked the victim to strip.

Toh himself also stripped naked, said Mr Yeo.

When the judge was about to pronounce sentence, Chaw wanted to speak but was told to do so through his lawyer.

Mr Yeo then told the court that Chaw wanted to highlight that the victim had lied about his age and sent over a fake photo of someone else in a Telegram chat.

District Judge Kenneth Chin acknowledged this but added that Chaw had not taken further active steps to ascertain the victim's age.

He said the objective of the offence was to protect minors from exploitation, regardless of whether the minor is an active participant or initiator.

"Absence of coercion is a neutral factor and is not a mitigating factor," said the judge.

He agreed with the defence that Toh had a slightly higher culpability than Chaw for their similar charge.

For sexual penetration of a minor, Chaw could have been jailed for up to 10 years, fined, or both.

For producing child abuse material, he could have been jailed for up to 10 years and fined or caned.

新加坡：一名退役陆军上尉经其前女友（海军厨师）介绍认识了一名 15 岁女学生，三人随后在多层停车场发生性行为。

此后，船长与这名未成年人保持联系，并多次与他发生性关系，还拍摄下来供自己“收藏”。

41岁的新加坡人周嘉俊于周二（10月20日）被判处17个月监禁。

他承认犯有三项罪名：性侵未成年人、唆使未成年人进行性侵以及制作儿童虐待材料。

法庭获悉，Chaw在2024年犯罪时39岁，是新加坡陆军上尉。

他的同案被告，26岁的Owen Toh Wei Song，是新加坡共和国海军的一名厨师。

Chaw 和 Toh 在 2021 年至 2022 年间交往，分手后仍保持联系。

2024 年 4 月左右，受害者是一名 15 岁的中四学生，他在网上搜索如何在网上交朋友。

他来到一个面向新加坡成熟男同性恋者的在线论坛，发现了 Toh 的个人资料。

他主动联系了Toh，两人开始讨论性方面的话题。Toh说他在某些特定领域没有经验，但Chaw有。

受害者同意与 Chaw 见面，Toh 谎称 Chaw 32 岁。

2024 年 6 月 5 日之前，Chaw 接上了 Toh，然后开车去接受害者。

随后，他们前往榜鹅的一个多层停车场，在那里，Chaw要求受害者脱光衣服。

随后，Toh与受害者发生了性行为，Chaw则在一旁拍摄。

Chaw 对受害者实施了性行为，随后三人穿好衣服离开。

事件发生后，Chaw 应 Toh 的要求，将视频副本发送给了他。

CHAW 再次遇见受害者

Chaw后来多次单独与受害者见面。

其中一次这样的遭遇发生在 2024 年 6 月 5 日，地点是某购物中心，他们进入残疾人厕所并发生了性行为。

Chaw拍摄了两段犯罪过程的视频，其中一段拍到了受害者的脸。

Chaw将这些视频保存在手机里。他后来表示，他拍摄并保存了自己与他人发生性行为的视频，并称之为他的“个人收藏”。

受害者的母亲和姐妹们开始担心他的行为，以及他收到的来自一名男子的礼物，而这名男子后来被证实是 Chaw。

被质问后​​，受害者向他的母亲和姐妹讲述了事情经过，然后于 2024 年 10 月 23 日向警方报案。

Toh上个月被判处12个月监禁。

论证的句子结构

副检察官马克西米利安·周要求判处周某 17 至 21.5 个月监禁，并指出性侵未成年人罪的存在是为了保护弱势群体——16 岁以下的未成年人。

辩护律师马克·叶奥表示，他对量刑的立场与检方的立场相差不远。

这是因为 Toh 是将 Chaw 介绍给受害者的人，也是停车场事件中更为积极的一方。

检方认为，停车场事件涉及“无端侮辱”，因为受害者当时赤身裸体地站在露天。

叶先生表示，该地点是“与受害者商议后”选定的，是杜某要求受害者脱光衣服。

叶先生说，杜先生本人也脱光了衣服。

法官即将宣判时，周先生想发言，但被告知要通过律师发言。

叶先生随后告诉法庭，周先生想强调的是，受害者谎报了自己的年龄，并在 Telegram 聊天中发送了别人的假照片。

地方法官陈建国承认了这一点，但他补充说，周某没有采取进一步的积极措施来确定受害者的年龄。

他表示，这项罪行的目的是保护未成年人免受剥削，无论未成年人是积极参与者还是发起者。

法官表示：“没有胁迫是一个中性因素，而不是一个减轻处罚的因素。”

他同意辩方的观点，认为 Toh 和 Chaw 犯有类似的罪行，但 Toh 的罪责略高于 Chaw。

如果Chaw犯下性侵未成年人的罪行，他可能被判处最高10年监禁、罚款或两者并罚。

他因制作儿童虐待材料，最高可被判处 10 年监禁并处罚款或鞭刑。
