Application process for return of property (gold jewellery)

Robbery took place at our residence in Nov-2021. Police officials caught the main accused by Jan-2022 and kept us visiting till Sep-2022. When we asked for the chargesheet copy, they kept on giving reasons and we assumed they didn't even submitted the case in court. Upon several follow ups, they shared the case no. with us (which we couldn't trace on Maharashtra court's website for a week, may be due to the reason that the didn't submitted the case till then). We visited the court multiple times for extracting the chargesheet only to understand that only approx. 25-30% of the lost items were recovered and logged in the chargesheet (though the police officers were very inconsistent in telling us what they recovered every time we visited for routine follow ups). Also, during our routine follow ups, they informed us that one of the local jewelers was involved in buying the stolen jewellery but his name was nowhere mentioned in the chargesheet. Now, we seek to get hold of all the jewellery recovered since we need it. Please suggest what we can do to 1. Ensure more jewellery is recovered/presented to court 2. Apply for return of property
