Tenant abscoded without paying rent

Sir, I rented my flat on 24/11/2020 to one Rahul Solanki, Hathras, UP-204216.(No Agreement) Till three months he paid the rent in time but we have to remind him everytime. After that he started delaying the rentby 5 to 10 days. He was everytime away on or before 24th of the month as it is the day rent was due evert month. His excuse was I am not well, my car broke down, had an accident etc. So, he did not pay the Rent and Mainetenance from April’21 onwards, nor did he pay electricity bill used by him. He also misbehaved and shouted on phone a couple of times. He now refused to pay anything and on so many requests and follow-ups he gave the keys of above flat to the main gate guard. When we checked the flat we find the following shortcommings 1. The Glass near to the kitchen wall was broken. 2. The tap was running free in the kitchen. 3. 3-4 Lights were not working in all. 4. So much garbage , unused food, trash letf inm the kitchen, rooms. 5. RO is missing. 6. Door handle of inner room missing. Hence , the total amount pending is Rs.17700/- (Rent, Electricity , RO, Repairs of Chimney , glass, tap etc….) What should we do now to recover the amount
