Senior BJP leader Sushil Kumar Modi on Tuesday demanded a probe into a plot of land that he claimed a man called Lalan Choudhary had "gifted" to RJD chief Lalu Prasad's wife, Rabri Devi.

Modi, on the sidelines of his weekly janata durbar, shared with reporters what he said were copies of the registered deed according to which Lalan, a resident of Barhariya in Siwan district, donated a 1,088.8-square-foot plot in Danapur on the western fringe of Patna to Rabri in January 2014. The land, valued at Rs 23.8 lakh according to the deed, has a 500-square-foot house worth Rs 7 lakh.

A part of the deed document, through which the property was purportedly donated by Lalan to Rabri, reads: "... the Donor is very close to the Donee for a long time and the Donee is also financially helping and rendering service to him for long time and therefore the Donor disclosed his intense desire to make gift his said property in favour of the Donee."

Modi demanded that Rabri explain what kind of financial help she had been giving to Lalan and also what ser-vice she was rendering to the donor.

The BJP leader also shared a copy of what he said was a registered deed that showed how Lalan had bought the land in 2009 from Ratneshwar Prasad Yadav, of Tarapur in Munger, for Rs 3.97 lakh.

The Telegraph has not verified the authenticity of the documents.

"This is perfect case of benami property in which one person uses one's money to purchase a property in someone else's name and then gets it transferred to one's own name," Modi claimed. "The state government should probe the deal."

The BJP leader also claimed he had sent his men to the village mentioned in the deed as Lalan's address and the villagers told them that Lalan used to work at the cowshed owned by Lalu's family.

"I have nothing to substantiate the information provided by villagers," Modi added.

He dared Lalu Prasad and his family members to share in public details about Lalan Choudhary.

Nitish Kumar has been chief minister of Bihar for so many years but no one is donating property to him whereas Lalu and family have several such assets donated by others, Modi claimed.

The BJP leader has been levelling allegation after allegation at Lalu, and when asked details of how many of Lalu family's property he would come up with, Modi answered, grinning: "Till people in government continue to supply the documents to me."
