Some domestic helpers are being linked to a string of burglaries in northern New Territories after 176 incidents were reported in the first quarter alone.
The suspects broke into their former employers’ home using duplicate keys, am730 reported Monday, citing the police.
They warned homeowners to replace door locks whenever they change helpers.
Thieves have been targeting villages in Tai Tong Road in Shap Pat Heung district and Tai Shu Ha Road East.
A family in Fairview Park in Yuen Long lost an estimated HK$200,000 (US$25,800) to robbers, the report said.
Senior inspector Law Yee-ling of the Yuen Long police task force sub-unit said burglary investigations are become increasingly challenging because thieves have become more sophisticated.
Besides breaking into houses through the front door, they mostly leave no tracks behind such as fingerprints and other potential evidence, he said.
Law said a large part of theft-related police work is crime prevention such as spot checks on security systems.
Police received 568 reports of home invasions in northern New Territories last year, down 33 percent from 2013.
The 176 break-ins in the first four months are down 22 percent from the corresponding period a year ago.
Of the 232 burglary cases in Yuen Long last year, 12 were solved with the arrest of 21 people.
Yuen Long reported 21 burglaries in the first quarter.
