AGARTALA, July 27 (TIWN): After Nitish Kumar sworn in as the BJP Chief Minister of Bihar, Tripura BJP State Observer Sunil Deodhar has asked Lalu Prasad Yadav to get prepared for Tihar jail leaving Bihar (Choro Bihar, Chalo Tihar). With a historical move BJP has finally occupied in Bihar, one of the most challenging states for BJP after West Bengal and Tripura. Sunil Deodhar referring Nitish Kumar's joining in BJP said, "It's good that although late, but Nitish Ji has chosen the right track". However on the other side, Lalu has accused Nitish Kumar for intriguing with BJP. Lalu also called Nitish Kumar as an "opportunistic".Venting his ire on the JD-U chief for dumping the Grand Alliance, RJD chief Lalu Prasad on Thursday alleged that Chief Minister Nitish Kumar had "conspired" with the BJP to get graft cases filed against his family by central investigation agencies.

"Nitish Kumar has cheated the people of Bihar. I charge that he (Nitish Kumar) colluded with BJP to file CBI cases against me and my family," Lalu Prasad told reporters after appearing before a CBI court here in a fodder scam case.

He said that Sushil Modi, who was sworn in as Deputy Chief Minister, was asked to run a campaign to damage the image of his family members.

The CBI, ED and the Income Tax department have filed cases of corruption against the family members of Lalu Prasad, including his wife Rabri Devi, his youngest son Tejashwi Yadav, who was Bihar Deputy Chief Minister until Wednesday, and daughter Misa Bharti.

Describing Nitish Kumar as 'Bhasmasur', Lalu Prasad said, "I made him the Chief Minister despite my party being the single biggest party in the state. 

"I was not selfish," he said.

Lalu Prasad's remarks came soon after Nitish Kumar and Sushil Kumar Modi took oath as Chief Minister and Deputy Chief Minister of a JD-U-BJP government in Bihar.

"When I was facing allegations, Nitish Kumar never called me or showed any sympathy. Friends are known to be sympathetic during tough times, but Nitish Kumar never paid heed towards me," he claimed. 

"Everything was fixed," Lalu Prasasd said, adding, "He is a very big opportunist. The mandate we got was against the BJP and the RSS. We jointly made them return empty handed from Bihar (during the 2015 Assembly election)."

He also claimed that Prime Minister Narendra Modi and BJP chief Amit Shah were "jealous" of him. "They knew that my base is unshakable. I never gave Nitish Kumar any problems," he added.
