Rashtriya Janata Dal (RJD) supremo and former Bihar chief minister Lalu Prasad Yadav was rushed to a hospital in Patna after his health deteriorated on Saturday morning, said reports.
Prasad, who has been convicted in three fodder scam-related cases, was released from Ranchi jail on May 16 after he was granted a six-week provisional bail by the Ranchi High Court. The bail was granted to the veteran politician on health grounds.
Reports said Prasad was admitted to the Indira Gandhi Institute of Medical Sciences (IGIMS) after he complained of breathlessness.
The 69-year-old leader is suffering from diabetes, blood pressure, kidney problems and other ailments.
The authorities at the Birsa Munda jail had separately granted the RJD chief a three-day parole on May 10 to attend his elder son Tej Pratap Yadav's wedding in Patna on May 12. The time taken to travel was not included in the duration of the parole and Prasad had returned to the prison on May 14, a day after his parole expired.
A special CBI court convicted Prasad on January 24 in the RC-68A/96 case, related to the fraudulent withdrawal of Rs 37.62 crore from the Chaibasa treasury, and sentenced him to five years of imprisonment.
The RJD chief was convicted in the RC64A/96 case, in connection with the fraudulent withdrawal of Rs 89.27 lakh from the Deoghar Treasury in the 1990s, and sentenced to three-and-a-half years in jail on December 23 last year.
The CBI court had held Prasad guilty in the RC 38A/96 case, pertaining to the fraudulent withdrawal of Rs 3.13 crore from the Dumka treasury in the early 1990s, and sentenced him to 14 years of imprisonment.
The RJD supremo has been in jail since December 23 last year, after being sentenced in the Deoghar treasury case.
