A prison guard was shot dead and another injured last night when a man opened fire at an outdoor cafe in Macau. The attacker, armed with two guns, fired four times at the pair as they and three colleagues ate at the Golden Ship Cafe in Rua do Commandante Mata e Oliveira shortly before 11pm. A 43-year-old warder died instantly. The injured man, 26, was in serious condition in hospital. Sources said a police officer witnessed the attack and gave chase. The two victims were said to be among a batch of officers deployed from Portugal four months ago to strengthen security.
