Patna: Lalu Prasad was on Monday discharged from AIIMS, New Delhi, and sent on his way back to Ranchi's Rajendra Institute of Medical Sciences (RIMS), a move which, the RJD chief alleged, was part of a political conspiracy hatched by the Narendra Modi government.

"There is a conspiracy against me by Narendra Modi and the CBI," he said, pointing out that he was being shifted to Ranchi despite poor health.

"I am being sent to RIMS which does not have any facility for treating kidney patients," Lalu alleged.

The RJD boss was sent back to Ranchi by the Rajdhani Express, the same train that had brought him to Delhi on March 29. Before being discharged, Lalu was paid a visit by Congress president Rahul Gandhi.

Lalu had earlier written to the AIIMS director, asking him to continue his treatment at the facility till he recovers fully. But AIIMS decided to discharge the RJD leader, saying his condition has improved significantly and he was "fit to travel".

Lalu's supporters created a ruckus on the hospital premises, alleging there was a conspiracy to "murder" their leader by "forcing him out" of the premier health facility. The supporters broke a glass door, abused the security guards and administration officials, hospital sources alleged.

The RJD is alarmed by the CBI move to shift back its chief to RIMS. "It does not make sense. He was shifted to Delhi for better medical treatment. Now suddenly he is being shifted back to RIMS Ranchi when he (Lalu Prasad) is yet to make a recovery. In fact the infection of his kidney has worsened," said Lalu's younger son and Bihar leader of Opposition Tejashwi Yadav, recalling that he had met his father in Delhi recently and was saddened to see his failing health.

RJD leaders are furious. "Does Lalu Prasad not have the right to his life? Almost 50 per cent of his kidney is non-functional, he suffers from dizziness and his blood pressure and sugar keep fluctuating. He will not run away from AIIMS, Delhi. There are no doctors capable of treating him in RIMS, Ranchi," said a senior RJD leader close to Lalu.

According to informed sources, the CBI was interested in getting Lalu back to Ranchi before May 4, when hearing for provisional bail for the RJD chief is scheduled to take place in Jharkhand High Court. RJD sources indicated that Lalu may not apply for parole to attend his elder son Tej Pratap's marriage scheduled on May 12.
