Recovering an amount of money from a friend while having only his full name

Dear sir/madam,

I am from the UK and a friend borrowed money in the region of £50,000 (GBP) and moved away to Dubai for supposed heart operations. I have WhatsApp messages with them promising to pay me back but they have since blocked me and done credit card fraud in my name and sent the money to themselves in Dubai.

3 out of the 5 banks have concluded their investigations here in the UK and confirmed I was a victim of fraud. I am still waiting for the remaining 2 banks to conclude their investigations.

In the meantime, I have lost my savings of £50,000 after helping a friend who claimed they needed money for Hospital Operations in UAE and bills, etc. I have bank statements to prove the money owed to me.

Is there anything I can do?

Thank you!
