Can you get a PCC if you leave the UAE with an unpaid loan and another closed case?

I need help getting a PCC for my uncle who needs it for visa/immigration to the UK. He used to live in Dubai but left in 2015 and never went back.

He did not finish paying a loan he had when he left. He had also been jailed in Dubai for a month after a drunken fight for which he paid the penalty charge before release.

Is it possible for him to get a clear PCC or not?

Please advise.
