Sushil Kumar Modi on Tuesday brandished documents that he said prove RJD chief Lalu Prasad usurped land in a housing cooperative society for state lawmakers.

The RJD scoffed at the charge, saying no rule had been violated in the society near Patna Veterinary College.

The society has 230 plots, measuring roughly 2,400sqft each and allotted through lottery to members of Parliament from Bihar and state legislators. The state government had provided land for the society on 30-year lease in 1987, which could be renewed if the rules are not violated.

While one plot (no. 208) in the society was allocated to Lalu in 1992, Modi alleged, another plot (no. 207), allocated to - now late - RJD leader Badshah Prasad Azad, was transferred to Lalu in 2010.

"How can one person get two plots when the bylaws of the society specifically talk of the one-person-one-plot rule?" Modi asked while speaking to reporters on the sidelines of his weekly janata durbar.

Bhola Yadav, the society secretary and RJD MLA from Bahadurpur Assembly seat in Darbhanga district, dismissed the allegation.

"The rule limits allocation but it does not say that someone cannot have another plot by means of transfer from the person who has a plot in the society," Bhola told The Telegraph. "Modi should stop misguiding people by quoting the rules selectively."

Several other politicians, including late Radhanandan Jha and late Nagendra Jha, too had their houses in the society on two plots but Sushil was intentionally targeting the RJD chief to catch attention of the media and his own party leaders, Bhola claimed.

Reacting to the BJP leader's allegation that late Azad had transferred the land to Lalu for a paltry sum of Rs 37,000, Bhola said: "Ours is a no-profit-no-loss society and the cost of taking a land on lease is Rs 37,000. We do not sell land to all and sundry."

Modi claimed that Lalu's wife, Rabri Devi, had also first got a plot transferred in her name from late Sudha Srivastava (plot no. 151), then transferred it to RJD leader Abdul Bari Siddiqui and had got Siddiqui's plot (no. 209), situated adjacent to the one allotted to Lalu, transferred in her name.

Two more plots (nos. 210 and 211) too were virtually in possession of Lalu, Modi claimed, as no. 210 had been allotted to Lalu's brother-in-law Sadhu Yadav and no. 211 to Lalu loyalist Prem Chandra Gupta. Bhola said while the plot allotted to Sadhu was vacant, the one allotted to Gupta was very much in Gupta's name and not in the name of Lalu or his family members.

Modi claimed that several properties in the society had been put to commercial use in violation of rules and maintained that the Patna district magistrate (DM) had submitted a report about it to the chief minister but the file had been kept pending for the past three months.

DM Sanjay Kumar Agarwal, posted in Patna since December 2015, however, denied submitting any such report.

Bhola also claimed he had not received any such complaint.

"We have not violated any rule or bylaw. The society has already submitted an application to the government for renewal of our housing society lease," he said.

Sushil demanded that the society be superseded and plots allocated "in violation of rules" be cancelled.
