Hundreds of Indian Police have tested positive for the coronavirus in recent days, raising alarm among an over-stretched force as it attempts to enforce the world’s largest lockdown to contain the pandemic.

Some three million police are trying to ensure that the vast majority of India’s 1.3 billion people stay home.

TV footage early in the crisis showed the Police beating back migrant workers as they tried to board city buses to reach their villages, making a mockery of social distancing.null

India has been under lockdown since March 25 and confirmed nearly 50,000 coronavirus cases and some 1,694 deaths.

A senior officer in the western state of Maharashtra said the number of cases had nearly doubled in the Police force there in the last week.

Maharashtra, the hardest-hit state, has reported a total of 15,525 infections as of Tuesday.

“More than 450 people from the state police force have now tested positive and four have died due to the virus,’’ the officer said, speaking on condition of anonymity.

Control rooms were being set up exclusively to deal with health issues faced by the Police in Maharashtra, according to the state’s Home Minister, Anil Deshmukh.

Police fired tear gas at a crowd of protesting migrant workers in the neighbouring state of Gujarat this week and launched baton charges against hundreds queuing at liquor stores in New Delhi, even as the first steps were being taken by state authorities to relax the lockdown to revive the economy.
