Two men stole diamonds worth an estimated $1 million from the owner of a trading company in Kwai Chung yesterday morning.
The 30-year-old proprietor of the business, which distributes diamonds and shoes, told police that two men in their 20s knocked on the door between 8am and 9am.
When he opened the door, they pushed him to the ground, brandished a bag containing what is believed to have been a gun, and bound his arms and legs with tape.
They took two bags of diamonds.
The proprietor freed himself and activated an alarm shortly before 11am. He was unhurt.
In another robbery at Tai Kok Tsui, five men rushed into an apartment where two female occupants had left the door unlocked.
The robbers, armed with hammers and knives, bound and robbed their victims. Four men whose visit to the flat coincided with the robbery were also taken captive.
They reported that valuables worth $42,400 were stolen - $12,700 in cash and the balance in watches, rings and mobile phones.
Police were alerted by a passer-by who saw the six victims crying for help inside their apartment after the robbers fled.
Police are seeking suspects aged from 23 to 30.
Despite yesterday's incidents, government figures show the crime rate has fallen recently.
The government revealed that in the first 10 months of this year, crime was down 8.3 per cent compared with the same period last year. This was attributed partly to the impact of economic recovery on the number of thefts, robberies and burglaries.
The figures showed violent crimes had fallen by 6.1 per cent, and a downward trend was also observed for robbery, theft, burglary and murder. But there was a slight increase in rape, criminal intimidation and offences related to the use of psychotropic drugs.
