Hong Kong is threatening to knock down the doors of residents who don’t respond to authorities conducting mandatory-testing blitzes as the city tries to end a persistent winter wave of coronavirus cases.

"The government can take legal action, including evicting or expelling individuals, or applying to the magistrate for a warrant to break into the unit,” the government said in a statement Tuesday.

The Asian financial hub has been attempting to curb a fourth wave of COVID-19 infections with targeted lockdowns that see authorities cordon off an area and restrict movement until residents receive negative results. The government has suggested some might be deliberately evading the tests in areas that range from densely packed neighborhoods to just a handful of buildings.
