Days after policemen pleaded with the administration to provide them with alternative accommodation so that they do not endanger their families, a building in police colony in the city was sealed on Sunday evening. With a constable serving at the Bangur Nagar police station testing positive, authorities cordoned off a building in the city's largest police colony in Naigaon, which houses the families of 10,000 personnel.

Police colonies in Worli and Marol have already been declared containment zones and 12 other police colonies are under the scanner.
