Maverick legislator Emily Lau Wai-hing was in hot water over her remarks on the right of Taiwanese people to decide their fate on the question of reunification, with the pro-Beijing community in Hong Kong mounting blistering attacks on her.
A district council member lodged a complaint with the police alleging she had breached her oath of support for the Basic Law when sworn in as a legislator in 2000.
Ms Lau wrote to the police commissioner to complain after vandals smeared faeces on the door of her Sha Tin district office last week.
Some of her Legco colleagues are considering an internal probe into whether her remarks constituted misconduct. A separate plan is being mooted by lawmakers to put a motion for a debate reaffirming Legco's support for the principle of 'one China'.
The two major pro-Beijing dailies - Ta Kung Pao and Wen Wei Po - have given extensive coverage to the controversy, with harsh words against her 'pro-independence' views.
The heat and emotion aroused by Ms Lau's remarks contrasted with the indifference to the Taipei conference before it was held in the middle of last month.
