Chattogram Metropolitan Police (CMP) declared eight areas under three police stations in the port city as "highly infected" areas for Covid-19 today.
The CMP officials were seen closing the gates of Jainagar Residential Area under Chawkbazar Police Station hanging a signboard saying "Red zone" this afternoon.
The CMP officials did the same at five residential areas in Rampur under Halishahar Police Station and two areas at Saraipara under Pahartali Police Station.
However, officials of Health department could not say on what basis CMP declared some areas as red zones for Covid-19 infection.
Dr Hasan Shahriar Kabir, director (Chattogram division) of Directorate General of Health Services, said they did not know how CMP declared the areas as red zones.
"We have not given any such instruction," he said.
Echoing the same, Chattogram Civil Surgeon Dr Sheikh Fazle Rabbi said it is not clear on what criteria CMP termed some areas as red zones.
"CMP cannot do it without our guideline or without our official consent," he said.
Bijoy Basak, deputy commissioner (west zone) of CMP said, "It was mistakenly written as red zones. Actually, we wanted to say highly infected areas."
When questioned on what criteria the areas were declared as highly infected, he said they collected data from civil surgeon office and identified the highly infected areas.
He was also questioned about the percentage of infection in the areas termed as highly infected and he said he would tell that after seeing the file.
Meanwhile, police restricted movement of residents in the "highly infected areas" after locking the gate. They said they will help people if they need to go out for emergency.
