I suspect a girl brought to Kolkata is a victim of human trafficking, what can I do under the state law?

Human trafficking is governed by West Bengal Premises Tenancy Act 1997 read with the central anti-trafficking provisions applicable in Kolkata. The Calcutta High Court has held that the state must rescue and rehabilitate trafficking victims. You can inform the anti-human trafficking police unit and the child welfare committee. The victim is produced before the committee for care and protection. The state must provide a safe home and counselling. The trafficker is prosecuted and the proceeds of the crime can be confiscated. The victim is entitled to compensation under the victim compensation scheme. Inaction is challengeable before the Calcutta High Court.
