HONG KONG: A man linked to Hong Kong’s  pro-democratic opposition was arrested in China in connection with a  plot to use a drone to disrupt a mainland delegation due to visit the  global hub, China’s state news agency reported on Sunday. The unnamed  man, arrested in the southern Chinese city of Shenzhen, was a “sponsor”  of Hong Kong’s opposition camp and worked with another opposition figure  to obtain the drone, the Xinhua report said. The purchase was part of a  plot to cause “disruptive activities” against the delegation. Xinhua  carried few details on the incident, which comes amid heightened  political and social tensions over perceived mainland interference in  the former British colony. The Xinhua report did not state which  mainland delegation was the target, but news of the arrest comes just  ahead of the visit to the city on Tuesday by Zhang Dejiang.
