PENANG: Sufiah Yusof, the child Maths genius who was found working as a hooker had been using the Internet to solicit for clients since December.

She also used a UK-based Internet sex forum and her own website "Exotic Manchester Asian escort" to promote her services.

However, the site, which she had registered and maintained herself, has been removed after News of the World broke the news of her working as a hooker.

Checks with the Internet registrar on domains revealed that Sufiah started the website on Dec 3 last year.

She bought the domain name for her webpage for two years.

Sufiah, 23, called herself Sufiah Marshall, borrowing the family name of her former husband, Jonathan Marshall, to register the website via a German domain handler.

The checks also revealed she had used a German server to host her website pages but with a United Kingdom domain name.

She had used the UK-based Internet sex forum to post her views being a "working girl" and her encounters with men, some of whom were aged between 50 and 60 .

In one of her postings, which was labelled as probationary member to the forum, in December, she said, "If I have to choose between a random older client and a random twenty something client (I) would probably go for the older guy!"

In her other postings, also in December, she provided vivid postings of her encounters and involvements as a ?130 escort girl who provided sex services.

Last week, a News of the World undercover reporter found her working in her Salford flat near Manchester and reported his encounter with Sufiah.

Sufiah, whose father Farooq is a Pakistani, and mother Halimathon is from Johor, was said to have called herself Shilpa Lee.

She also advertised herself as "a sexy, smart student".

The story in the newspaper came just days after her father was jailed for sexually assaulting two 15-year-old girls as he home-tutored them in Maths.
