Hindu Marriage in 2015, Separation in 2016. My wife left some clothes in matrimonial home. Locker keys are with her but last few transactions were done by me as she used to give key to me to get jewellery out of the locker. My parents stay in separate state but some jewellery of my wife is with my mother,my wife kept it there as we didn't have locker at that time and whatever jewellery she kept with my mother was not very useful. In 2018, she filed a FIR with several sections including 498A, 406, 420. After filling of FIR, my lawyer and mother went to Mahila thana where SHO gave a list of items handed over by the girls side to notify what is in her possession. SHO asked to return the items in my mother's possession. We hired a new lawyer and he says that we don't have to return anything because if we return now after FIR with 406 then we will prove ourselves accused. How are we accused when IPC 405 was not followed. No demand notice, no oral or written letter. Please advise.
