Bhujbal was granted bail by the Bombay High Court on May 4 after being in jail since March 2016 in connection with a case under the Prevention of Money Laundering Act (PMLA).
"He experienced pain in the chest and breathlessness," sources added.
The former state Public Works Department minister was arrested in March 2016 after an Enforcement Directorate (ED) inquiry revealed that he and his associates allegedly misused their office and caused financial loss to the government.
According to the ED, Bhujbal had awarded contracts related to construction and development works, including one for the construction of the Maharashtra Sadan in New Delhi, to a particular firm, in return for kickbacks for himself and his family.
