Need assistance

Actually a person filed a police complaint against my cousin for selling the visa and beating him up. The court dismissed the visa case due to lack of evidence, but in the fighting case, the court imposed a fine of 5000 riyals on him. My cousin did not pay his fine and appealed to the court to remove the fine. But one day the police checked his identity and sent him to jail for being fine. Now tell me what should we do? Some people say that the police will definitely deport him. Some people are saying that don't pay the fine and spend 2 months in jail. So advise me what should I do? Whether the fine should be given and whether the police will deposit him? What will be all possible conditions?
