Next time a courier phones to say he can't find your office, think twice before you head out to the main entrance to collect the package from him.
Police are warning that burglars are using this ploy to sneak into offices in commercial and industrial buildings in eastern Kowloon, taking advantage of victims who leave their doors open when going to meet the bogus courier.
The thieves snatch valuables, usually wallets and mobile phones left on or around the reception counter.
Chief Inspector Chan Wai-man said there had been five such burglaries in Kowloon Bay, Kwun Tong and Ngau Tau Kok. No one has been arrested.
He said the thieves had checked out the offices beforehand and chosen ones with just one or two staff.
Chan said his Kowloon East Region had recorded a total of 308 burglaries in the first half of this year, down from 321 during the same period last year.
Most of them were in Wong Tai Sin and Sau Mau Ping.
Chan said about two-thirds of burglaries in public housing estates happened during daytime, when only housewives or elderly were at home. Many happened when residents opened their doors for ventilation,
Chan said village homes in Tseung Kwan O and Sai Kung recorded the most burglaries among the 62 village house burglaries in East Kowloon in the first six months. He said most of these properties had lax security, such as no security guards and CCTV. He urged people to install alarms or CCTV, and change the lock of their gates if possible.
