With reference to an incident that happened in Bhandup last week, a non-governmental organisation has alleged that agencies appointed by the Brihanmumbai Municipal Corporation (BMC) were using cruel and improper methods to catch stray dogs for sterilisation. Plants and Animal Welfare Society (PAWS) has written a letter to the Animal Welfare Board of India (AWBI) and the civic body, asking them to take action against the people, who were indulging in such cruelty.
