Three policewomen disguised as compensated-dating girls have arrested about 20 men - including an off-duty policeman and an immigration officer - on suspicion of soliciting for immoral purposes.
The arrests were made on Monday and Tuesday after the suspects sought dating partners on internet forums and smartphone applications asking for girls who wanted to make quick money, police said.
"They offered a few hundred dollars to meet when our undercover policewomen answered and expressed interest," an officer said. "[They met on the streets and] the suspects offered more money for sex. They were caught after taking our undercover agents to love hotels."
One of the suspects is an off-duty policeman, aged 40, who is attached to Sham Shui Po police station.
He was arrested on Monday after offering HK$2,000 for sex in a meeting with an undercover policewoman and then taking her to a love hotel in Yau Ma Tei.
The constable was released on bail pending further investigation. It is understood that he will be facing disciplinary action.
An immigration officer was also nabbed in the police sting, but the police did not provide more details.
During the undercover operation, police arrested a 17-year-old student who used internet forums and smartphone apps to prostitute himself to women. The Form Five pupil was nabbed when an officer posed as a client to meet him.
Police also deployed two undercover officers who posed as clients to arrest two schoolgirls.
Chief Inspector Alan Chung from Kowloon West regional crime unit said the two girls said on internet forums or smartphone apps that they could provide sexual services for HK$1,000 to HK$1,500.
Chung said the three students would be referred to the Social Welfare Department for further action.
During the operation, police arrested a total of 28 people, including pimps who claimed they could introduce patrons to women (who were actually undercover officers).
