The accused, who allegedly owns a brothel in Agra, was also asked to pay fines of NRs 150,000 ( Rs. 94,000) to each girl.
Nepal Police had arrested Tamang one-and-a-half years ago after the six girls who managed to escape from the brothels in Agra reached home and lodged separate cases.
Justice Ananta Raj Dumre maintained that the sentence could be extended further if any more girls sold by Tamang files cases against him.
