MUMBAI (Reuters) - 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.

Some 3 million police are trying to ensure that the vast majority of India's 1.3 billion people stay home, with TV footage early in the crisis showing police beating back migrant workers as they tried to board city buses to reach their villages, making a mockery of social distancing.
