New Delhi: Delhi Chief Minister Arvind Kejriwal on Monday welcomed the FIR against him in the water tanker scam, saying it only proved Prime Minister Narendra Modi realises that his direct confrontation is the AAP leader. "Mujhe Khushi hai ki apne sweekar kiya ki aapki ladai sidhe mujhse hai (I am happy you have accepted that your direct confrontation is with me),” Kejriwal said in a tweet after the Anti-Corruption Branch (ACB) on Monday registered a FIR against him and his predecessor Sheila Dikshit in connection with the scam. Citing the famous couplet "Sarfaroshi Ki Tamanna Ab Hamare Dil Mein Hai, Dekhna Hai Zor Kitna Bazu-e-Katil Me Hai", Kejriwal also posted: "Modiji we do not fear your agencies like CBI, ACB." In a series of tweets, the Aam Aadmi Party chief said: "All the probe agencies are under your (Modi) control. You have unleashed CBI, police and ACB on me. You got a CBI raid conducted on me (but) got nothing. Now we welcome your FIR." He also targeted the Prime Minister for not acting against Congress president Sonia Gandhi and her son-in-law Robert Vadra. "Modiji you did not file FIR against Vadra, you did not register FIR against Sonia, You did not file FIR in any scam mentioning which you become the PM,” Kejriwal tweeted.
