Two convenience store workers in Hong Kong have been arrested in connection with a series of theft and fraud cases in recent months in which tourists or pub-goers in Lan Kwai Fong were targeted. On Saturday, officers detained a woman, 55, in Tsim Sha Tsui on suspicion of “conspiracy to defraud”, one day after a man, 21, was arrested in the same district over similar matters. Officers identified the duo as convenience store workers who had facilitated the use of stolen credit cards. Tourists in Lan Kwai Fong and Wan Chai have HK$360,000 stolen in sex stings by African asylum seeker and friend Police declined to confirm on Sunday if the pair worked at the same convenience store. Both were released on bail and required to report back to police in mid-June. In a related move, police on Friday also arrested an African expatriate, 23, accused of using a stolen credit card to buy goods worth some HK$1,300 (US$167) at the convenience store manned by the 21-year-old man at the time, authorities said. The credit card in question was previously reported stolen in March by an Indian woman, 38, after she visited popular entertainment district Lan Kwai Fong. The African man was charged with one count of obtaining property by deception and is expected to appear at Eastern Court on Monday. Police investigations are under way and the force said on Sunday that more arrests could follow. The trio in custody were believed to be members of a syndicate behind a number of theft and scam cases in Central in recent months. Victims were tourists and pub-goers. Another expatriate man, 35, suspected of being the leader of the syndicate, was arrested in Tsim Sha Tsui last Tuesday and expected to appear in court on July 6.

The pair, aged 27 and 28, were also expected to appear in court on July 6. Police told the Post earlier that some cases could have gone unreported, especially when victims did not lose a large amount of money. There was no evidence that victims in the recent cases had been drugged. But police advised pub-goers to be wary of having their drinks spiked with narcotics, such as the date-rape drug, Rohypnol, by strangers who approach them. The drugs are tasteless, odourless and colourless. They cause victims to become disoriented or unconscious, and they can also induce memory blackouts. Under the influence of the drugs, victims are persuaded to use or hand over their bank cards and PINs.
