Delhi Police on Friday refused to file a complaint against central minister VK Singh for his controversial remarks over the death of two Dalit children in Haryana, the AAP said.

An Aam Aadmi Party delegation urged the assistant commissioner of police in Karol Bagh to register a First Information Report against the minister of state for external affairs under the Scheduled Castes and Scheduled Tribes (Prevention of Atrocities) Act, 1989.

"We requested him to register a complaint, to which he said it needed the DCP’s permission," AAP leader Ashutosh told the media. 

"The officer said he will first conduct an enquiry and then will seek the DCP’s permission to register a case against Singh," he added. 

Singh triggered a huge row on Thursday when he used an analogy of stoning a dog while commenting on the burning of two Dalit children in a Haryana village by upper castes.

As the opposition demanded Singh’s sacking from the Narendra Modi ministry, the BJP MP apologized saying he was sorry if he had hurt anyone’s sentiments.

Ashutosh said the former army chief’s apology was politically motivated. 

"He did not apologize from his heart. Rather it was politically motivated. He apologized after (former Bihar chief minister) Jitan Ram Manjhi sought his apology. 

"He apologized seeing the importance of the Bihar elections for his party," Ashutosh said.

The AAP leader said Singh crossed "all limits of decency" when he made the remarks over the Dalit children’s killings.

"He has no business to be in the cabinet. He should be arrested. We requested police, which falls under the central government, that Singh’s status should not determine the fate of this case," he added.
