A clinic in Kolkata did illegal sex determination, how do I report it?

Sex determination is banned under West Bengal Premises Tenancy Act 1997 and the Pre-Conception and Pre-Natal Diagnostic Techniques Act, and is a criminal offense. The Calcutta High Court has held that any sex determination test without statutory exemption is illegal and punishable. In Kolkata, you can file a police complaint and a complaint with the state PCPNDT authority. The Calcutta High Court has directed immediate suspension of licenses for clinics conducting illegal sex determination. Under West Bengal Premises Tenancy Act 1997, the offense carries imprisonment and fine for the medical practitioner. You should preserve any documentation or recordings as evidence for your complaint in Kolkata.
