My sincere advise to you would be to ask your father to surrender before the police, and obtain regular bail. He is not guilty of any wrong doing, he purchased a property that was sold to him by an agent in 2008, how did your father know that to the very same land there are other owners, the charges being levelled against him cannot be proved if the matter goes to trial.
Once he surrenders the court will automatically assume that he is innocent and grant him regular bail, once out on bail, your father can think of working out a out of court settlement so that he does not have to go to court for the rest of his life.
according to me this would be the best approach.
