The government said that during a morning operation at two buildings on Nathan Road - Tsim Sha Tsui Mansion and Mirador Mansion, police and officials checked the test records of around 700 residents and found over 120 had violated a recent compulsory testing notice.
Fines of HK$5,000 and new testing orders were dished out to the alleged offenders, along with a warning that non-compliance can lead to a larger fine of HK$25,000 and six months in prison.
"The government understands that the enforcement process may cause some inconvenience to the residents, but hopes that the residents can understand," a statement said.
According to reports, Covid cases have emerged from the two buildings earlier, with some of the patients being overstayed visitors holding recognizance forms, or commonly known as "going-out passes", issued by the Immigration Department.
More than one million new cases of the deadly virus were recorded last week across the 51 countries included in WHO's European region.
