MAINLAND police have arrested five suspects in the HK$28 million (US$4.8 million) kidnap-for-ransom of Hong Kong clothing heiress Queenie Rosita Law, moving fast after one of the alleged gang members was nabbed by Hong Kong authorities Sunday.

    Three of the suspects, all from the mainland, were apprehended in Guangdong Province at a time not yet specified by police, while the two others were arrested in a hostel in Shenzhen’s Luohu District on Monday, the South China Morning Post reported yesterday.

    But it’s not clear if all five actually took part in the kidnapping of Law, granddaughter of the late Bossini founder, Law Ting-pong, from her Sai Kung house April 25.

    The sixth, a 29-year-old man from Guizhou Province identified only by his surname Zheng, was picked up in Hong Kong when he tried to cross into Shenzhen through the Lo Wu checkpoint Sunday night.

    It’s also unclear whether authorities have recovered the HK$28 million in ransom payment that the kidnappers fled with after releasing their captive.

    Mainland police arrested the five suspects after their Hong Kong counterparts sought their help in tracking down the kidnappers last week.

    Law was abducted when six Mandarin-speaking men broke into her house and stole more than HK$2 million in cash and valuables.

    The kidnappers held Law in a secluded cave in Fei Ngo Shan before they called her father and demanded more than HK$40 million for her release. That amount was later reduced to HK$28 million.

    A police source said Zheng was responsible for bringing food and drink to the victim and the rest of the kidnappers.

    “He walked downhill from Fei Ngo Shan to Choi Hung where he bought food and drink, and then he walked uphill to their hideout in Fei Ngo Shan,” the source said. “We were told he bought bread and hamburger for the victim.”

    Law was released last Tuesday after her father paid the ransom. Police then launched a massive search for the kidnappers.

    Hong Kong is for the most part considered to be safe, with violent crimes in 2014 falling almost 10 percent from 2013. Robberies also fell 38.2 percent to 309 cases in 2014, compared to figures from 2013.

    But a series of high-profile kidnapping cases shocked the city in the 1990s.

    The eldest son of the city’s richest man Li Ka-shing was kidnapped in 1996 by the infamous crime boss Cheung Tze-keung, nicknamed “Big Spender,” who also kidnapped property tycoon Walter Kwok in 1997.

    Cheung fled to the mainland but was later arrested by mainland authorities and executed in 1998.(SD-Agencies)
