Eight suspects stood trial in the mainland province of Guangdong on Thursday over the kidnapping of a Hong Kong heiress last year.
Shenzhen Intermediate People's Court in Shenzhen City said the eight suspects had admitted to being involved in the abduction of Queenie Rosita Law at her house in Hong Kong on April 25 last year.
Law, granddaughter of late textile tycoon Law Ting-pong, was later released after a ransom of 28 million Hong Kong dollars (3.6 million U.S. dollars) was paid.
Eight members of the gang were arrested on the Chinese mainland, while another was netted in Hong Kong. Among the eight tried on Thursday, six were charged with kidnapping and two with handling illegal gains.
According to prosecutors, the gang had been planning to kidnap someone in Hong Kong since March, 2015. In the early hours of April 25, they broke into Law's residence, where they also stole watches and jewels. Law was held in a cave before being released three days later.
