Activists arrested during a demonstration to save the doomed Star Ferry pier in Central say the prospect they could each face two criminal charges over the protest would not dissuade them from fighting on in their bid to save Queen's Pier from demolition this month. Activist Chau Hoi-dick said police informed them yesterday they were widening their investigation to include the offence of misconduct in a public place. Police earlier said they were investigating the activists on suspicions they obstructed a police officer in the execution of his duty. Chau, a freelance writer, and 12 other activists were arrested on December 15 celebrating the 49th anniversary of the pier's opening. The 13 protesters, including Ho Loy, editor of the Lantau Post, were detained when they clashed with police while trying to reach the gate of the demolition site. Ho, a single mother, was first arrested two days earlier after canvas sheeting at the site was allegedly slashed with a box cutter. This week she was charged with one count of criminal damage and one count of possessing an offensive weapon over that incident. She will appear in Eastern Court on Wednesday. Ho, of the Heritage Watch group, reported to police yesterday and learned she may face two further charges over her arrest with the 12 others present in the early hours of December 15. 'They cannot stop me from carrying on the fight to save the Queen's Pier,' she said. Chau described the latest development as a 'political decision'. 'They are trying to deter us and the people of Hong Kong from continuing our fight to protect Queen's Pier and demanding the government reconstruct the Star Ferry pier,' he said. The activists tied their hands with red cloth and covered their mouths with red bandages on a march yesterday from the Waterfront Police Station in Sheung Wan to Central. A dozen supporters, including legislator 'Long Hair' Leung Kwok-hung, joined the march.
