Describing the alleged rape and murder of a doctor at Kolkata`s RG Kar Hospital as a "painful" incident, Vice President Jagdeep Dhankhar Friday called for a deterrent ecosystem to punish the perpetrators for such crimes.

Dhankhar’s remarks came after the Congress on Sunday slammed the Modi government over the Hindenburg Research’s allegations against SEBI chairperson Madhabi Buch, with Gandhi saying the integrity of the market regulator has been “gravely compromised” and demanded a JPC probe into the matter.
