I was renting a room from a retired police inspector, but he stole my laptop with all my work files. I have proof against him and two other tenants who helped him. I need to get my laptop back and be compensated for the losses I’ve suffered because of this theft.

You can file a police complaint for theft under Section 379 of the Indian Penal Code. You can also sue the landlord and the other tenants in a civil court for damages and to recover your laptop. You should gather all evidence and seek legal advice to proceed further.
