The alleged Shenzhen gunman suspected of targeting two prominent Hong Kong citizens was swarmed by dozens of police when they discovered a homemade pistol in his bag, a court heard yesterday. Taxi driver Kong Ka-chung described a chaotic scene as officers drew their weapons and pointed them at Huang Nanhua, 50, before he was pinned to the ground at a roadblock on the evening of August 14. Mr Kong had just picked up Huang and was driving along Dundas Street in Mong Kok when the taxi was stopped, he said. 'Police officers lunged forward and pinned him to the ground,' Mr Kong testified in the Court of First Instance. 'There was a brief struggle.' Constable Mak Tsui-yee said she noticed Huang immediately when she looked into the taxi. 'He moved his body downward and looked very suspicious. When I looked at him, he evaded eye contact,' she said. Huang has pleaded not guilty to carrying a firearm and ammunition with the intent to commit an arrestable offence. Such offences include shooting with intent and kidnapping, prosecutor Peter Chapman has told jurors. The court has heard that when arrested at the roadblock, Huang was carrying a gun and personal details of publishing tycoon Jimmy Lai Chee-ying and former Democratic Party chairman Martin Lee Chu-ming. Mr Lai's picture and an office address for Mr Lee were among the items found in Huang's bag. When a police sergeant searched Huang's bag on the seat of the taxi, the sergeant had yelled out 'be careful' in Cantonese and told surrounding officers to draw their guns, Constable Mak testified. 'We understood that [the defendant had] a gun or a pistol,' she said. Huang had fought efforts to subdue him and had resisted when an officer handcuffed him, she said. 'He moved around and was not that co-operative,' Constable Mak added. 'He refused to be handcuffed.' Huang had kept struggling as three officers pinned him to the ground. Sergeant Jiu Siu-kin denied that he or other officers had assaulted Huang after his arrest. Barrister Francis Cheng, for Huang, described a prolonged beating from the time Huang was put in a police van to when he was interrogated by Sergeant Jiu. On Wednesday, Huang's friend, Chan Yuk-por, said the alleged gunman had told him that he was ordered to throw his homemade pistol into the sea after he had finished 'holding somebody'. It was unclear if Mr Lee or Mr Lai were the targets of a kidnapping. The trial continues before Deputy Judge Peter Line.
