My business partner in Kolkata ran away with company funds what criminal case can I file

Misappropriation of company funds by your partner in Kolkata constitutes criminal breach of trust under Section 316 of the Bharatiya Nyaya Sanhita. You should file an FIR immediately at the relevant police station in West Bengal, providing audited accounts, bank statements, and board resolutions proving the funds were entrusted to the partner. The complaint should detail how the partner dishonestly disposed of the property. You can simultaneously file a civil suit for recovery of the funds. If the police are unresponsive, you can approach the Magistrate under Section 223 BNSS or the Calcutta High Court under West Bengal Premises Tenancy Act 1997 for directions.
