The parents of Lalit Jha, who is the fifth accused in the major security breach of Parliament, have claimed that their son was not involved in the incident. "He is a very good boy. Due to his studies, he also received an award from the Mithilanchal Parishad. He used to teach at a coaching centre. We came to know (about the incident) yesterday after he was arrested," Jha's father Devanand Jha said.
