The Indian Museum in Kolkata was sealed on Friday after a CISF officer posted there died of COVID-19, an official said.
Thirty-three CISF personnel deployed at the gallery's security unit have been asked to self-quarantine, Indian Museum director AD Choudhury told PTI.
The museum is closed since March 14.
"... After a report of a CISF jawan testing coronavirus positive, these security personnel have been quarantined," the director said.
The entire museum premises and the security quarters are being sanitised and the staffers have been asked not to come to the office for the time being, he said.
