Kejriwal, who joined hundreds of people at Jantar Mantar demanding action against guilty, said necessary action would be taken against those responsible behind the attack on the basis of the magisterial enquiry already ordered by Delhi government.
"It is a very unfortunate incident. It is not only the fight for people of North East. It is our fight. We all have to fight it (racial discrimination)," he said. Nido Tania, a first-year student of a private university, had died after he was allegedly assaulted by a group of people in Lajpat Nagar.
"I saw the news on television. We ordered independent magisterial enquiry within an hour... We did not order it under any pressure. Some people wrote to me why should we order another enquiry when police is already probing it.
"I told them Delhi Police is interested party. It is one of the accused. The Delhi police cannot conduct independent investigation. Therefore, we ordered magisterial enquiry," he told the gathering. The Delhi government had on January 31 ordered the enquiry to probe Nido's death.
"The enquiry would be completed within 3-4 weeks. If a policeman is found involved in it, action would be taken against him," Kejriwal said.
Without taking any names, the Delhi chief minister also charged "netas" for making promises who are meeting protesters and pledging actions in the case.
"All these 'netas' who are coming here. They would say this would be done, that would be done. This will not happen. There has to be a justice this time. If there is no justice in the case, then there won't be any justice in the future.
Congress Vice President Rahul Gandhi had on Monday joined the protesters at the Jantar Mantar and assured them that the government would ensure that they get respect and justice.
