From the South China Morning Post, via Asia Media:
A group of activists petitioned the central government’s liaison office yesterday calling for the early release of Hong Kong-based journalist Ching Cheong…
About 500 people have signed an internet petition calling for Ching’s release during the past week, and the alliance plans to step up the campaign at the district level.
The Security Bureau has written to the group, saying it was in touch with Ching’s family and would provide help whenever possible.
