A student was jailed for 22 months on Monday after assaulting her prostitute friend's client who had demanded sexual services that she did not agree to.
Nur Azilah Ithnin was studying aerospace machining technology at ITE Central when she was part of a group who kicked and punched Mr Didier Moise Dominguez after he booked a session with Nuurul Aliyyah Abdul Talib, 23.
The French product line manager suffered a broken jaw and a black eye in the attack, spending four days in hospital.
Azilah, 20, had been concerned for her friend's safety so she and her accomplices accompanied Aliyyah to Marina Boulevard to meet the 53-year-old.
Later Aliyyah called them for help to "get out of her predicament" after refusing one of Mr Dominguez's demands.
Along with Aliyyah's brother, Ahmad Habiibul Hakim Assalafi, Malcolm Graham Head and his girlfriend, Veronica Patricia Rio, she rushed over to the Marina Bay Residences and attacked Mr Dominguez.
Wielding a knife she took from the kitchen, Azilah kicked the client. Hakim punched him and then covered the victim's face with a black shirt, telling his friends that whoever wanted to hit the man could do so. Azilah kicked him again, while Head punched him in the nose.
All five are said to be part of an online vice ring and Azilah was the first to be dealt with.
District Judge Siva Shanmugam jailed her for causing grievous hurt at around 1am on March 4 and consuming methamphetamine, or Ice, the previous day.
Hakim, 19, is scheduled to plead guilty on Oct 2, while cases against his sister and her alleged pimps Head, 33, and Rio, 19, are at pre-trial conference stage.
Azilah has previous convictions for harassment on behalf of loan sharks and mischief by fire.
