Update | Bossini heiress kidnap suspect arrested at Hong Kong border as remaining fugitives ‘smuggled back to mainland’

Several of the six kidnappers responsible for the multimillion-dollar ransom and abduction of Hong Kong's Bossini fashion chain heiress, Queenie Rosita Law, have been smuggled back to the mainland, the Post has learned.

The revelation surfaced after one of the fugitives was intercepted at the Lo Wu border checkpoint when he tried to leave for Shenzhen at about 10.30pm on Sunday, only to be arrested.

Last night, the five other suspects - believed to be from the mainland - remained at large and in possession of the HK$28 million paid in ransom for the return of Law last Tuesday night, despite police mounting a huge search operation in Sha Tau Kok, near the border between Hong Kong and Shenzhen.

It is understood that some of them had left for Shenzhen through illegal channels and that the rest were hiding out in Hong Kong.

The arrest of one of the suspects was announced yesterday by new police chief Stephen Lo Wai-chung, as police investigations revealed that the cave where Law, 29, was held for three days was dug by the kidnappers at Fei Ngo Shan, at the southern end of Ma On Shan Country Park.

"Investigations showed one of the kidnappers received a call from his accomplice to confirm they had received the ransom, and then he carried the victim downhill and released her," one police source said.

He added that the victim was blindfolded and tied up at the time. Police had not located the cave as of last night.

The 29-year-old man arrested on Sunday night holds a two-way permit, the travel document mainlanders use to visit Hong Kong. He is understood to have come from Guizhou province.
