Recovery of a smartphone

I Had given a BlackBerry keyone smartphone to a Female friend after she had shown me her broken Smartphone, which was not working at all . The smartphone which I had given her is a brand new sealed packed phone , which was being purchased by my father for Rupees 44 Thousands . And I had given it to her without my father’s knowledge and consent. After my Father came to know about this incident . He scolded me very much and asked me to bring back that smartphone along with its box and the accessories. After that I phone called my friend and told her the whole matter and had asked her to return the phone along with its original accessories. She agreed to return the smartphone and asked me to call back 3 days later from the present date, because on that time she had gone to visit her maternal uncle. She was to come back after 3 days . So she requested me to call back after 3 days. 3 days later when I once again called her back , this time she had an excuse ready on her tip of the tongue she said that due to some covid 19 positive cases on her uncle’s locality, she is unable to leave the area. So she and the other members of her uncle’s family had to spend three weeks on quarantine. And that she will return home after one month. So I was asked to call back after that time period. I began to wait for one month. After 30 days got over I called her back ,this time her sister picked up the phone and told me that they are still on their uncle’s home. And asked me to come to their uncle’s home to collect only the phone and it’s charger. When I asked her that what happened to the other accessories of the phone and it’s box? She told me that her elder sister had lost the box and Also the earphones along with it. And after that she disconnected the call before giving me the exact address of her uncle’s house. From the later half of that day to still today nobody of the two sisters are answering my phone calls or calling me back . Also I don’t have her home’s address so me and my father are unable to visit her home. What can I do now , will I involve the Police in this matter and file an FIR in the local Police station against her for the theft of the property, cheating etc? Or should I file an Mobile phone missing complaint with the Police?
