Police in southern China have arrested seven men including the suspected mastermind of a foiled gun plot targeting veteran Hong Kong democrat Martin Lee and media tycoon Jimmy Lai, a newspaper reported on Sunday.
The South China Morning Post newspaper cited unnamed police sources in the southern Chinese boomtown of Shenzhen as saying they arrested a Hong Kong man suspected of being behind the plot, along with six alleged accomplices with links to organized criminal gangs.
“It is unclear whether his six alleged accomplices are Hong Kongers or mainlanders, but all have strong links to Hong Kong’s triad societies,” the newspaper cited a person familiar with the matter as saying.
