"There should be an impartial probe into the suicide to bring out the truth," Singh said when asked to react on the suicide of Ram Singh.
Ram Singh, an accused in the December 16 gang-rape of a 23-year-old girl in a moving bus who died in a Singapore hospital on December 29, allegedly committed suicide in the Tihar Jail this morning.
Ram Singh was arrested soon after the December 16 incident from near his home in R K Puram.
"This Congress government has destroyed all healthy practices in a democracy," he said.
