"Our ladies are cute, young and passionate ... Come and play at any time," reads the north shore brothel's website.

Dozens of young women, mainly of Asian descent, worked at the brothel. According to its website, many were students or in their early 20s and described as "so gorgeous" in the website's reviews.

But police will allege sex work was only part of the business' appeal.
