Frederick Fung Kin-kee has become the latest figure from the pan- democratic camp to be barred from entering Macau.
Mr Fung, Kowloon West lawmaker for the Association for Democracy and People's Livelihood, previously visited Macau in early November. He was detained at the city's ferry pier on Saturday and later told to take the next ferry back to Hong Kong.
'Macau is too sensitive. I have never been rejected entry to any cities,' he said, adding that he had returned from a trip to Harbin in December.
He sought help from Stephen Lam Sui-lung, Secretary for Constitutional and Mainland Affairs, but was told that the Hong Kong government had no jurisdiction over other governments. A former chairman of the association, Mr Fung was told that his name had 'appeared on a computer' and was denied entry under Macau's internal security laws.
The lawmaker, who was with a friend from Shanghai, was intending to meet the association's former staff on Saturday. His friend was allowed entry.
The security panel of Hong Kong's Legislative Council will ask the Security Bureau to invite Macau officials to explain why some Hong Kong residents have been denied entry to Macau. The panel's next meeting will be held early next month.
