NCP leader Chhagan Bhujbal was on Monday admitted to Mumbai's Lilavati Hospital for further treatment.
Chhagan Bhujbal, who got bail last week after spending more than two years in jail in a money laundering case, was accompanied by his MLA-son Pankaj Bhujbal.
The Bombay High Court granted him bail in a money laundering case on May 4, and the senior politician underwent treatment at the civic-run KEM Hospital before being discharged five days later.
The 70-year-old Nationalist Congress Party leader is accused of misusing his position to launder Rs 857 crore during the redevelopment of the Maharashtra Sadan, which is the state guesthouse in New Delhi. He allegedly accepted kickbacks through firms owned by his relatives.
