Wrongfully accused of assault. How to prove innocence?

Greetings,

In 2018, I was wrongfully accused of assault. My colleague got into a fight with a local man outside of a restaurant. I never got involved but was somehow accused of assaulting this person.

When I spoke to the prosecutor, I mentioned that there were several CCTV cameras that would prove that I never assaulted anybody but was told that "the CCTV cameras weren't working on that day".

I was jailed for 20 Days, released on bail, and left the UAE without going to court in fear for my life. I recently requested my records which indicate an arrest warrant, 20,000 AED fine, 2 months in Jail, and a deportation order.

I understand that the best way to have this settled is to file an appeal and appear before the judge. My biggest concern is what happens once I arrive in the UAE for the appeal.

Will I be arrested and jailed again and potentially in a worse situation than before?

I really would like to finally get this properly resolved so if anyone has any suggestions, I would love some advice.

Thanks!
