New Delhi, Sep. 13 : The bail hearing of former Samajwadi Party general secretary Amar Singh, who was arrested for his alleged role in the 2008 cash-for-vote scam, will be heard by a lower court on Tuesday.

Singh, who is suffering from kidney-related problems, has been admitted to the All India Institute of Medical Sciences (AIIMS) following a rise in creatinine level in his body.

Singh is seeking interim bail from a Delhi court on medical grounds. The CBI is likely to ask for further custody.

Creatinine is a fairly reliable indicator of a person''s kidney functioning.

Singh, 55, was admitted in the private ward of AIIMS at around 8 p. m. on Monday, Tihar Jail spokesman Gupta said.

A panel of doctors at Tihar jail examined Singh, found his creatinine level high and decided to refer him for admission in AIIMS, Tihar sources said.

Dr S Gupta, head of the Nephrology of AIIMS, is attending on Singh.

Singh was arrested on September 6 in connection with the cash-for-vote scam. (ANI)
