ADDITIONAL charges, including false imprisonment, were laid against some of the defendants alleged to be connected with December's grenade explosion and shootout in a Tsuen Wan police raid. Yeung Kit, 27, Leung Sui-chiu, 24, Ng Kam-fook, 23, Yau Chor-shan, 20, Fung Kai-lok, 27, and Cheung Kar-yee, 20, are jointly charged with possessing firearms and ammunition without a licence in a 23rd floor flat at Tsuen Wan Centre on December 2. Yesterday, 11 new charges including four counts of robbery were laid against some of the defendants in Tsuen Wan Court, taking the total number of charges to 20. The five male defendants face a joint count each of making use of ammunition with intent to resist arrest and using a firearm with intent to resist arrest. Yeung, Leung, Ng and Yau are also charged with false imprisonment and committing an offence while in possession of firearms. They were accused of imprisoning Mr Kong Sai-wing in a car on September 30 last year. Yeung and Ng each face a count of dangerous or reckless use of arms and ammunition. Ng and Yau are jointly charged with forcibly taking away and detaining Ms Yeung Hoi-ling on June 28 last year in Aberdeen for a ransom and wounding her with intent. The prosecution also withdrew a count of attempted murder against Leung, a count of robbery against Fung and a count of possession of explosives against the five male defendants. Yeung, Leung, Ng and Yau had been charged with two joint counts of robbery. Leung and Yeung are also charged with a count of attempted robbery and four counts of robbery. The alleged armed robberies were said to have happened at four goldsmith shops between June 25, 1991, and May 29 last year, involving more than $3.97 million worth of gold ornaments. Magistrate Mr Henry Brazier adjourned the case until February 24 when the defendants are expected to appear in Eastern Court for committal proceedings. The five male defendants were remanded in jail custody while Cheung had her bail extended at $30,000 cash and $20,000 on her own recognisance. Cheung's mother also stands surety for her at $50,000 on her own recognisance. She was ordered not to leave the territory.
