Recovering the amount of a bounced cheques after someone fled the UAE

I had a non-dated cheque given by an Indian individual against the money given to him for his trading business promising that he will give some profit every month and return the money within six months.

However, he failed to give monthly profit after two months and I came to know that he cancelled his residence visa and planning to leave the country.

I have presented the cheque (312K AED) at the bank and got insufficient funds note and registered a criminal case at a Dubai police station. However, next day morning he left to India through Emirates Airlines.

I am still wondering how he could leave when travel ban is there which I was told that will be automatically effective once I get case number which I got the previous day. I came to know from other friends that he has a plan to migrate to Canada soon.

What are the next steps I should take to recover my money?
