New Delhi: The heavy stone-pelting, violence and arson witnessed in parts of Delhi on Monday were a conspiracy to defame India at a time when US President Donald Trump is visiting, minister of state for home G Kishan Reddy has said.Hitting out at Opposition parties for backing the protests against Citizenship Amendment Act, Reddy told ANI: “This is a conspiracy to defame India. Why are these protests taking place at a time when the US President Donald Trump is visiting the country … Will the opposition parties take responsibility for the death of the Delhi Police constable? Will Congress take responsibility?”Delhi Police head constable Rattan Lal was killed in the violent protests on Monday. A native of Sikar, Rajasthan, the 42-year old was posted in the office of assitant commissioner of police, Gokulpuri. Many police personnel, including Shahdara DCP Amit Sharma, were injured in the violence. Sharma is now okay, said a source.Holding out the assurance that the law and order situation in affected parts of the city had been brought under control, home secretary Ajay Bhalla said: “Senior officers of Delhi Police are in the field with adequate Central para-military force personnel, managing the situation.”According to sources in the government, the violent anti-CAA protests appear to be orchestrated to coincide with Trump’s India visit in a bid to garner headlines in the international media. Stone-pelting and crowds of protestors started building up on the eve of US president’s arrival and intensified as his special flight was about to touch down in India. This, many point out, cannot be a coincidence.“This is a matter of investigation,” an officer said when asked what had triggered the crowd-build up and violent protests on Monday. He stated that while things got a little tense in the afternoon, with an attempt to set fire to a petrol pump and riders moving around with country-made weapons, “the situation was subsequently brought under control”. Sources said Delhi Police will be registering cases in connection with the violence and arson and the suspected perpetrators arrested.Discounting the possibility of Delhi Police have failed to act in time to control the violence, a senior government official said the police casualties are testimony to the fact that the police was in the thick of the action against the violence-mongers.Incidentally, sufficient Central forces personnel were already deployed in the Capital in view of Trump’s visit, when the violent protests broke out.Meanwhile, offering his condolences on the death of head constable Rattan Lal, Reddy tweeted: “My deepest condolences to the family of the Delhi Police Head Constable who lost his life amidst the protests in Delhi. Our @narendramodi government condemns all forms of violence and we assure a stern action against the culprits”.
