A £2,000-a-week call girl who built her own brothel empire with sex dens across the UK has been stripped of her criminal profits.

Sun Sun Wong, 45, pocketed £2,000 a week as a vice girl before becoming the boss of a nationwide brothel network, ran with corporate precision.

The business management graduate, from Malaysia, rented properties in London, Birmingham Manchester, Guildford, Cambridge and Edinburgh which were used as upmarket sex dens.

Claiming her only income came from working as a masseuse, the former prostitute also purchased a £95,000 home.

Over a two year period, more than £400,000 was deposited into Wong's bank accounts, often at the weekly rate of £2,500.

But her destructive empire crumbled when she was busted by police and jailed for five years in February 2018.

Wong, who moved to the UK as a student aged 17, was convicted of controlling prostitutes for gain and converting criminal property at Cambridge Crown Court.

Now she has been ordered to pay back £442,000 of her ill-gotten gains. Peterborough Court gave her three months to find the sum at a proceeds of crime hearing this week.

DC Andrew McKeane said the cash order "demonstrates that crime doesn't pay."

He added: "It has ensured that Wong will be stripped of the profit she made from her crimes, and is a fitting conclusion to the appalling offences she has committed.

"This type of crime affects all walks of life but especially the vulnerable, who turn to the sex industry in their lowest moments."

Smartly dressed Wong once presented the persona of a successful and driven businesswoman and her upmarket dens flew in the face of the public's perception of brothels.

One complex, based in Midsummer Court, Cambridge, was marketed as “superb apartments in a sensational landscaped setting" with a nearby boat club and ancient willow tree.

Residents living in the historic setting were oblivious to the brazen sex-for-sale business burgeoning under their noses with grubby ads posted on adultwork.com.

When asked about her significant earnings, Wong said "I am very hardworking"

Yet the apartment's owners, who rented the flat to Wong, soon had concerns.

In a letter to Wong, they said: “We are very distressed at what has been going on at the flat.

“The flat is in a terrible state and needs totally redecorating, as well as repairs. You should not have been sub-letting our property which is totally illegal.”

Wong's publicity blurb on adult.com proved her downfall following a police sting operation.

Posing as punters, undercover officers arranged to meet three women at Midsummer Court under Operation Mantis, a Cambridgeshire crackdown on the illicit sex trade.

One detective said: "When we went there we found a Chinese national, who didn’t speak English.

“She didn’t have a passport, which we would expect for a Chinese national. She didn’t even know which city she was in and she had methamphetamines with her as well, which is a drug we never see in Cambridge.”

He added: "She wasn’t ever leaving the flat. She was in that flat to service customers at the bequest of whoever was controlling her."

In February 2016, officers had faced a similar scenario when meeting with a woman in Birmingham.

They found Wong's mobile phone number was directly linked to accounts set-up by prostitutes working in Birmingham and Cambridge, revealing her as the controller.

Speaking in court through a Cantonese interpreter, Wong denied the crimes and blamed a woman named Anita who had stolen her identity.

But she admitted being a former Birmingham vice girl earning £2,000 a week and said she also had legitimate employment as a waitress and masseuse.

Appearing in the dock, the mum-of-three said she had endured a string of personal tragedies.

The court heard after her first marriage broke down, she embarked on a new ten-year relationship, raising three children with a man she met while working at a Chinese restaurant.

Her eldest daughter was half-blind and cannot speak due to a genetic disorder, one son has asthma and the youngest suffers from a urinary tract infection.

Wong said she left the children’s father and began moving around the country, settling in London, Birmingham and then Edinburgh.

She lost custody of the children and only saw them every two months.

And Wong had an explanation for the wealth she continued to amass on a masseuse's pay packet, with significant financial support from concerned family and friends.

She said: "I am very hardworking. I work 24 hours a day because I don’t want to worry about problems with my children.

“Anytime I am unhappy I go to work, and when I am working I forget my unhappiness.”

DI Nick Skipworth, from the Cambridgeshire force, said the case highlights the sex industry's switch from street corners to cyber sites.

He said: "This is a national issue. In the 70s you might have had a pimp on a street corner controlling a group of women, and now you get the same thing, but internet-based."
