下次再有这种人直接开手机录视频。然后送警察局。

差一个字差得很远。
性骚扰的罪名全称叫做这个：

Word or gesture intended to insult the modesty of a woman
509. Whoever, intending to insult the modesty of any woman, utters any word, makes any sound or gesture, or exhibits any object, intending that such word or sound shall be heard, or that such gesture or object shall be seen by such woman, or intrudes upon the privacy of such woman, shall be punished with imprisonment for a term which may extend to one year, or with fine, or with both.
[Indian PC 1860, s. 509]
暴露癖，讲色情笑话等等，基本上归于此类。

动手的那种（就是传说中的非礼）是这个：
Assault or use of criminal force to a person with intent to outrage modesty
354.—(1) Whoever assaults or uses criminal force to any person, intending to outrage or knowing it to be likely that he will thereby outrage the modesty of that person, shall be punished with imprisonment for a term which may extend to 2 years, or with fine, or with caning, or with any combination of such punishments.
[51/2007]
(2) Whoever commits an offence under subsection (1) against any person under 14 years of age shall be punished with imprisonment for a term which may extend to 5 years, or with fine, or with caning, or with any combination of such punishments.
[51/2007]
[Indian PC 1860, s. 354]

仅限刑法典而已。
公司法来自澳洲。
程序法来自英国。
反正到处抄。

但是新加坡是普通法国家，很多法律是写在案子里面的。那些只能问律师。
