The BJP leader had developed certain symptoms and his samples were tested for coronavirus. He has been admitted to a private hospital here, after the report came positive.
Recently, Hazra was appointed as a national secretary of the party.
A few days ago, he made a controversial statement by saying he would hug Chief Minister Mamata Banerjee if he tests Covid positive. After that the Trinamool Congress had lodged a police complaint against Hazra for maligning the image of a public figure, who is a woman, and for violating the Constitution.
