Chief Judicial Magistrate Ram Gopal Singh also slapped a fine of Rs.10,000 on Salem.
The court Tuesday convicted Salem under section 471 of the Indian Penal Code and 12A of Passport Act for using a forged document and travelling without valid documents.
Salem has already served around three years in prison and after this sentence, he would have to spend one more year in jail in this case.
District prosecutor Rajesh Raikwar, however, expressed dissatisfaction with the punishment. "We will go in for appeal to increase the punishment," he told reporters.
