BJP National Secretary Siddharth Nath Singh Sunday challenged TMC MP Derek O’Brien to hold a protest march in the city over the alleged rape of a nun, the way he did in New Delhi after a church was destroyed there. “The alleged rape is a condemnable incident, but I will like to question O’ Brien if he will carry out a protest march in Kolkata as he did in Delhi. If he carries out the march, I promise that I will join it,” he said. [related-post] O’Brien, when contacted, said he did not need to react to what Singh had stated, but said, “Chief Minister Mamata Banerjee is in constant touch with the Archbishop of Kolkata since yesterday. This is a highly condemnable incident.” “I myself am in touch every few hours with the Archbishop of Kolkata, senior church officials in Delhi and also nuns of the Convent of Jesus and Mary. The state government has acted swiftly. The highest levels of administration will do all what is needed to find and book the culprits. The CID and the police are doing their job,” O’Brien added. Centre, state not acting as per gravity of situation: Congress Congress leader P C Chacko Sunday condemned the alleged rape of a nun and the ransacking of a convent school in West Bengal and sought “extreme punishment” for the culprits. “Extreme punishment should be awarded to the culprits. The governments (in the state and at the Centre) are not acting according to the gravity of the situation..Their lapses are more evident (in this case).That is the most unfortunate part of it,” he told reporters here. He said the anti-social elements responsible for this should be urgently apprehended, an enquiry carried out “without any loss of time” and punishment awarded expeditiously.
