HONG KONG (XINHUA) - A senior officer of Hong Kong police on Monday (Jan 6) refuted again accusations by a Hong Kong lawmaker that undercover officers disguised as rioters and committed violent acts on New Year's Day.

"Such accusations were utterly false and founded on fake news," Chief Superintendent Kwok Ka-chuen of Police Public Relations Branch said in a letter to Claudia Mo, a member of the Legislative Council of the Hong Kong Special Administrative Region.
