About 40 demonstrators set out from Chater Garden on a march to Wan Chai Police Headquarters yesterday protesting at charges laid against marchers in January. The six were charged with 'misbehaviour in public areas' after protesting against poor safety controls in mainland toy factories outside a Toys and Games Fair held at the Hong Kong Convention and Exhibition Centre. Mung Siu-tat, rally spokesman and one of the six charged, said they would try their best to safeguard the rights of demonstrators. 'The police can't keep us off by charging us, ' he said. 'Peaceful demonstrations are a basic civil right. We will not only continue to exercise our rights, but we will gather more people to fight for it,' Mr Mung said. The group plans to demonstrate tomorrow in Tsim Sha Tsui, outside the Hong Kong Toys Association, and on Thursday outside the Eastern Court. The six people charged in January, as well as some trade unionists, were rallying against the toy factories' poor safety measures when security guards removed them. The six were later charged and will appear in court on Thursday.
