Calling the Samajwadi Party supremo and Uttar Pradesh's chief minister as "bechare (helpless)", Gaur said: "What can Mulayam and Akhilesh do (to prevent rapes)?"
Talking to reporters, Gaur said that "rapes happen when a man loses his mental balance".
Mulayam Singh Yadav Wednesday courted controversy after he told reporters, who sought his comments on the Badaun rape case, to focus on doing their jobs.
What can Akhilesh and Mulayam do to prevent rapes, asked Gaur
Two minor girls were gangraped and hanged from a tree in a village in Uttar Pradesh's Badaun district that led to widespread criticism of the state government over crime and violence against women.
On Wednesday, Mulayam Singh snapped at reporters: "I am doing my job, you should do yours."
"Strict action is being taken (in the case). What else can I say," he added.
His remarks came after his son told reporters earlier that they should "Google" search the number of rapes happening elsewhere in the country and stop focusing on Uttar Pradesh.
