The family of Parliament security breach accused Lalit Kumar Jha on Saturday said it would move court for justice, claiming he is innocent.

Lalit, 38, a Calcutta resident and tutor, has been arrested in Delhi and accused of masterminding Wednesday’s storming of the Lok Sabha by two smoke canister-carrying youths.

“He (Lalit) is our sona beta (good son) and a very simple person. He cannot do anything wrong,” Lalit’s mother Manjula told reporters at the family’s ancestral home in Bihar’s Darbhanga district.

“He is innocent. We will approach the courts for justice.”

On Friday, a Bihar police team had arrived at the house in Rampur Uday village, searched the premises and questioned the family and other villagers about Lalit’s antecedents.

Sources said the police did not find anything incriminating. Nor have they found any previous case or complaint against Lalit in the police stations of the district.

Lalit and his co-accused have been booked under the anti-terror law UAPA and various sections of the Indian Penal Code.

Lalit lived in Rabindra Sarani, Calcutta, with his parents, providing private tuition to schoolchildren and also teaching at a coaching institute.

His 70-year-old father Devanand Jha is a priest who earns a living by performing religious rituals for clients.

Lalit is the second of three brothers: the eldest works at a clothes shop and youngest is an electrician.

Devanand said Lalit had put him and Manjula on a train on December 10, packing them off to their home village, while he himself travelled to Delhi citing some business.

“(Lalit) was a bright student. We wanted him to prepare for the medical entrance exam, but he quit studies because of our poverty and began giving ‘home tuition’ to children in Calcutta to support the family,” Devanand said.

“He later obtained a BA degree. He is good-natured; he donated blood three times for strangers.”

Lalit is said to have gone to Nagaur in Rajasthan after the security breach but returned to Delhi and surrendered before the police.

“We came to know from television and other people that he had been named in the Parliament security breach case. This is unbelievable. He never kept bad company,” the father said.

The police team was led by Biraul sub-divisional police officer Mahesh Chandra Chaudhary, who declined comment citing the sensitive nature of the case.

Calls and messages to Darbhanga senior superintendent of police Awakash Kumar went unanswered.
