A young woman was jailed for 22 months on Monday for attacking a French national and taking methamphetamine. Nur Azilah Ithnin, 20, was the first among five in an online prostitution ring case to plead guilty to causing grievous hurt to product line manager Didier Moise Dominguez, 53, and for drug-taking in March this year.

Investigation showed that the Institute of Technical Education (Central) student had been a close friend of Nuurul Aliyyah Abdul Talib, 23, and her brother Ahmad Habiibul Hakim Assalafi, 19, since secondary school.

Through them, she met Malcolm Graham Head, 33, and his girlfriend Veronica Patricia Rio, 19, who allegedly ran a vice ring. Aliyyah worked for them as a callgirl. On March 3, Aliyyah was asked to go to Marina Bay Residences to provide sexual services to Mr Dominguez who had made a booking for her for two hours at $280.

Worried about her safety, Azilah and her accomplices decided to accompany Aliyyah to Marina Boulevard. Due to some misunderstanding between the victim and Aliyyah, she was not agreeable to provide certain sexual services to Dominguez and called her accomplices for help. Azilah, Head, Rio and Hakim turned up and bashed up the victim who suffered fractures on his jaw. Azilah had kicked the victim's body twice while the others punched and kicked him. One even stamped his face and used a wine opener to hit his forehead three times.

The victim approached security at around 1.20am to call an ambulance. He was warded for four days and given 28 days' hospitalisation leave.

The five were arrested at Arab Street on March 5.

Hakim's case is scheduled for mention on Oct 2 and a further pre-trial conference has been fixed for the rest this week.
