In another development to the Alwar lynching incident, the Supreme Court on Friday issued notice Centre and other six states and sought response within three weeks.

A top court bench issued notice to Rajasthan, Maharashtra, Gujarat, Karnataka, Jharkhand, UP and sought a detailed report on a petition seeking ban on cow vigilante groups.

According to reports, Home Minister Rajnath Singh on Thursday told the Lok Sabha that the Centre would ensure that justice prevails in the lynching case in Rajasthan's Alwar.

"The state government has taken cognisance of the matter. FIR has been registered and some arrests have been made in the case. Centre would try that justice would prevail," Singh said.

Congress vice president Rahul Gandhi on Thursday condemned the killing of a Muslim man in Alwar and said the government should take strict action against those responsible for the brutal and senseless attack.

"When government abdicates responsibility and allows lynch mobs to rule, tragedies of immense proportion follow. Shocking breakdown of law and order in Alwar," he said.

Leader of Opposition in Rajya Sabha Ghulam Nabi Azad accused the Bharatiya Janata Party government of ignorance, saying that the entire world knows about these attacks except them.

Madhusudan Mistry of the Congress raised the matter during Zero Hour and said that the self-styled 'gau rakshaks' were harassing and killing people in the name cow protection.

Pehlu Khan, a 50-year-old man, died on Monday in Alwar, Rajasthan, after being brutally beaten up by a group of self-proclaimed 'gau rakshaks'. Khan was a part of a group of men that was transporting cows in a highway in Rajasthan's Alwar on Saturday.
