Justice I S Mehta granted the relief to the accused after perusing the reports of All India Institute of Medical Sciences (AIIMS) and Fortis hospital here, which said that Bhardwaj requires to undergo Stereotactic Radiosurgery (SRS) which is a non-surgical radiation therapy used to treat functional abnormalities and small tumors of the brain.
The hospitals' response came on the court's query made two days ago on the accused's plea seeking interim bail on medical grounds.
The police had opposed his plea for interim bail saying he might escape if he gets out.
Bhardwaj, 36, Deepak Bhardwaj's younger son, was arrested in April 2013 for his father's murder at a Delhi farmhouse on March 26, the same year.
The Bahujan Samaj Party (BSP) leader was gunned down by contract killers Sunil Mann alias Sonu and Purushottam Rana alias Monu at his 35-acre farmhouse in south Delhi. He was one of the richest candidates in the 2009 Lok Sabha election, having declared assets worth Rs 600 crore.
