The local administration has locked down Haripur upazila as a huge number of people returned from different coronavirus-hit districts.
Upazila Nirbahi Officer Md Abdul Karim made the announcement on Friday.
The UNO said people who worked in different districts, including Narayanganj, returned in the last several days. The decision has been taken to prevent the spread of coronavirus.
He said the returnees have been asked to stay in home quarantine.
