Beijing police will put aside regional restrictions to combat prostitution, gambling and drug trafficking.

"Each district-level police station will be able to track down and deal with pornography across the city, which should put to an end to corruption," said Li Runhua, head of the Security Corps at the municipal public security bureau.

City police, the business commission and other relevant government departments held a meeting on the regulation of entertainment places on June 9, in which 1,400 related corporate managers took part.

During the meeting, officers told the professionals about three specific rules: The police will not provide confidential information to entertainment places, will not intercede on their behalf, and will not be swayed by social connections, Li said.

"If we find that officers have been invited to entertainment places, accepted property or placed obstacles in the path of justice, they will be subject to serious disciplinary punishment and can lose their jobs."

Li said that from the outset of the prostitution crackdown on April 11 up to June 30, officers closed 39 entertainment places that allegedly organized, housed and offered prostitution.

In addition, police investigated 266 KTV clubs for broken equipment and poor security, and closed 445 hair salons fronting for brothels.

Another 580 gambling machines were seized.

In the same period, a total of 290 suspects - who allegedly organized or were involved with prostitution - were detained by police, with a further 2,000 suspects held for breaking public security.

Li said the number of calls to 110 concerning prostitution have dropped by 40 percent from the same period one year ago.

However, he said some entertainment places continue to wait out the crackdown. Many are obeying tighter regulations by improving their security systems, while simultaneously holding illegal activities in offices and employee dormitories. Others have closed for "redecoration".

The next move by police will be to check employee authorization cards (IC cards) and ensure that names provided are accurate, Li said.

"Entertainment spots must also have fully functional CCTV devices capable of saving images for 30 days, or

they will be shut until they meet the standard set," he said.

"From 9 pm to midnight each night, unscheduled visits to KTV clubs by police will hit their peak in terms

of frequency. Officers will search the premises completely."

Police will also carry out a special clean-up in the city's bars, including those in Luoguxiang, Houhai, Sanlitun and the area around Beijing Foreign Studies University, in Haidian district.

The 39 closed KTV clubs will be regularly checked to make sure they don't reopen under a different name or through a different registered owner.
