The owner of an adult entertainment venue billed as Hong Kong's first sex doll brothel has shut up shop after being arrested.

A police spokesman said a 30-year-old man was arrested following an anti-obscene objects operation. A police source said the man was arrested not for the sex doll business but for publicly displaying sex toys for sale.

The venue, called 'This Mary,' charges an hourly rate of HK$480 for clients to use one of three silicone sex dolls on the premises. Male clients can bring a female companion for a 90-minute session with a doll for HK$860.

The owner of an adult entertainment venue billed as Hong Kong's first sex doll brothel has shut up shop after being arrested.

It came two days after the Post visited the venue, This Mary, in an industrial building in Kwun Tong.

A police spokesman said a 30-year-old man was arrested following an anti-obscene objects operation at a flat in the Hoi Luen Industrial Centre at about 6pm on Friday.

Three television sets, 18 suspected indecent objects, and three memory sticks were seized.

On Wednesday, a Post reporter saw the televisions being used to show pornographic films inside three private rooms in which the dolls were placed.

The owner was released on bail and must report back next month.

Three sex dolls, all called Lucy, have their moving parts controlled by remote control at the WMDOLL factory's display room in Zhongshan, Guangdong Province, China. Aly Song/Reuters The proprietor, a Hongkonger who gave his name only as Rex, said on Saturday police approached him, offering an explanation he described as "something really nonsensical."

He did not elaborate further.

He said he was surprised by police's swift reaction, which came the same day as reports on his business appeared in the press.

This Mary charges an hourly rate of HK$480 for clients to use one of three silicone sex dolls on the premises. Male clients can bring a female companion for a 90-minute session with a doll for HK$860. The items are also for sale for between HK$18,000 (US$2,300) and HK$30,000 (US$3,800).

Rex, who started the business in September in the 1,000 sq ft flat, said he would consult friends for advice but could not say whether or not he would resume business.

A police source said the man was arrested not for the sex doll business but for publicly displaying sex toys for sale without properly covering them, as required by the Control of Obscene and Indecent Articles Ordinance.

He was also arrested for providing pornographic films to customers.

Three sex dolls on the premises were not seized because no relevant laws seemed to be applicable for police to act on, the source said.

But police would consult the Department of Justice, together with concerns the business might have violated the Hotel and Guesthouse Accommodation Ordinance, which states premises offering accommodation for a fee for a period of less than 28 days must be licensed, along with other possible offences.

Barrister Albert Luk Wai-hung said police could only act on the owner's suspected peripheral offences relating to the sex toys and pornography in question because they found no solid ground to act on regarding the on-site sex doll rental business.

The raid was aimed more at issuing a warning to deter its further development.

Luk said while the entrepreneurial spirit of young people ought to be encouraged, there were also ethical issues to be considered.

In Europe and North America, such controversial new businesses were expelled by landlords for moral rather than legal reasons.
