Rashtriya Janata Dal (RJD) leader and former Bihar deputy chief minister Tejashwi Yadav on Monday said he was worried about his father Lalu Prasad’s “falling” health.

The RJD chief has been undergoing treatment at the Asian Heart Institute in Mumbai for more than a week, a hospital spokesperson said.

“Visited my ailing father admitted in Asian Heart Institute, Mumbai due to various diseases. Perturbed to see his falling health & increased infection. Praying that he may recover soon under the around-the-clock monitoring & continuous medical care of specialist doctors,” he tweeted.

Lalu is presently serving sentence in three fodder scam related cases and was behind the bars since December 23, 2017. On March 29, he was hospitalised in Rajendra Institute of Medical Sciences (RIMS), Ranchi, after his health deteriorated and was later referred to AIIMS, New Delhi, for his treatment.

Lalu’s family members including wife and former CM Rabri Devi had alleged that the government was hatching a conspiracy to kill Lalu by not providing him proper treatment during his incarceration and had thus sought bail for getting him better medical care.

On May 11, the Jharkhand High Court had granted a six-week provisional bail to Lalu for his treatment at specialised institutes, though his counsel’s had sought a 12-week relief.

Laster on August 17, the Jharkhand High Court extended the provisional bail of former Bihar chief minister till August 27. Granting the extension of the provisional bail, the bench of Justice Apresh Kumar Singh fixed August 24 as the date to hear the bail petition.
