Brother's address was provided for getting a loan and it is not paid. Can he travel to the UAE?

Hi,

I have 2 credit cards in the UAE.

Due to Covid-19, I returned to my home country without paying my dues.

When I was requesting a credit card, I provided my brother's mobile no and address in my home country to the bank person.

Now randomly, the bank is contacting my brother about my bank dues.

The issue is my brother wishes to come to Dubai for work. If he comes to Dubai, may the police or bank catch him and ask for my bank dues?

Or can my brother work in Dubai without any issues and enter without any issues?

Please explain to me!
