The Bombay High Court on Tuesday said the Mumbai police, probing instances of fake vaccination camps against Covid-19 in the city, must identify the "big fish" in such cases and should not spare them.

A bench of Chief Justice Dipankar Datta and Justice G S Kulkarni also directed the Brihanmumbai Municipal Corporation (BMC) to inform the court about steps that the civic body proposed to take to check those duped by such camps for antibodies and any adverse effects on their health because of the fake vaccine.
