Left UAE with loan and credit card due

I was working in UAE in a good firm. I planned to stay there for 5 years as i had many debts in India.. I took loan in Dubai and cleared all my debts in India. I repaid the loan EMI for an year. I lost the job in UAE due to melting market scenario. I attended many interviews, but didn't get job. Without having any other option I just left Dubai.. Bank sent me many email about EMI due which is ₹ 20 lakhs. They have presented my security cheque and it got bounced. Now they have filed case against me in UAE. Now recovery agents in India are calling me. I don't know what to do. But am unable to save anything from the salary am getting in India At present am unable to repay the loan. What will be the concequences now? 1. Can recovery agent file a police complaint against me in India (at hometown) for not letting them to contact me. 2. I don't have any property in my name, in this case how they will recover? 3. Will I get arrested for this? I haven't done this purposely or intentionally. I lost my job. 4. What will be the final result in this kind of case?
