HONG KONG, Nov 19 (Reuters) - New Hong Kong police chief Chris Tang took office on Tuesday with a warning that “fake news” was undermining the reputation of his police force.

Tang replaces outgoing Commissioner Stephen Lo amid a fiery standoff with anti-government protesters at a university, and following five months of intensifying protests against the Hong Kong and Chinese governments in the Asian financial hub.
