FIREARMS used by Chinese Public Security officers have been found in Macau after police intelligence agents raided a flat in the Portuguese enclave. Agents found the weapons - which included several Chinese electro-pistols, a starting pistol which can fire bullets, and six pairs of handcuffs and knives - after receiving a tip-off. A 22-year-old will appear in court tomorrow. Meanwhile, police fired a shot to break up a gang fight in Macau yesterday morning. According to police, the fight started when a man and woman left the Si Toi Commercial Building, which housed several nightclubs, saunas and massage parlours, and were set upon by seven men. Police fired the shot when their order to stop was ignored. No one was injured and three people were taken to police headquarters to assist with investigations.
