Two off-duty police officers were stabbed outside a massage parlour in Macau's first outbreak of violence since the handover 10 days ago. When the officers, attached to the Immigration Department, rang the doorbell at the parlour on the 21st floor of Nga Lim Garden Estate on Tuesday, three men armed with knives rushed out. The officers, surnamed Yeung and Chu, in their 30s, suffered stab wounds to their heads and hands and were yesterday in a satisfactory condition in the Sao Januario Hospital. During the struggle, officer Yeung drew his service revolver but it was snatched by one of the three young attackers, who then fled. It was unclear why the off-duty officer had his gun with him. Detectives recovered a blood-stained knife, a piece of cloth soaked in blood and a set of keys belonging to one of the officers at the scene in the Avenida do Ouvidor Arriaga. The attack was the first incidents of violence since Macau reverted to Chinese administration at midnight on December 19. The new Government, led by Chief Executive Edmund Ho Hau-wah, has pledged to wipe out violent crime.
