Activists from the April 5th Action Group vowed yesterday to force their way into restricted areas around the handover venues. The pro-democracy group and two other small groups said they had set the Hong Kong Convention and Exhibition Centre extension as the destination of a march that starts at 10 pm on Monday. The two other groups call themselves 'Never Forget June 4' and 'People's Constitutionalist Society'. April 5th spokesman Leung Kwok-hung said: 'We will certainly be outnumbered by police, but we want our voices to be heard by Chinese leaders, as well as guests attending the ceremony. 'We will not be afraid . . . and if anyone is arrested it shows that the SAR government will not tolerate calls for people to take responsibility for the 1989 crackdown,' he said. Mr Leung said Chinese leaders had failed to investigate the June 4 massacre and were continuing to prosecute dissidents such as Wang Dan and Wei Jingsheng. 'We will chant slogans asking Jiang Zemin and Li Peng to step down in order to soothe the people's grief and anger. 'As a civilian, we have the right to ask our leaders to take responsibility for their wrongdoings and step down.' Mr Leung said the demonstration areas designated by the police beside Wan Chai ferry pier and outside Wan Chai Tower were too far from venues and too small to hold protesters. Roads between East Tamar and the Convention Centre extension will be sealed off from Sunday night to Tuesday evening.
