Taking to Twitter, Kejriwal also claimed that the Modi government has been targeting him instead of registering FIR against likes of Sonia Gandhi in any case, and asserted that he is not afraid of the "CBI and ACB of Modi".
"Modiji, you did not register FIR against (Robert) Vadra, did not register FIR against Sonia, did not register FIR in any cases, citing which you became the PM.
"I am glad that you have admitted that your fight is directly with me," he said in a series of tweets.
Kejriwal's comments come after a case was registered today by Delhi's Anti-Corruption Branch in connection with the alleged 400-crore water tanker scam linking former Delhi Chief Minister Sheila Dikshit.
ACB chief MK Meena said two complaints were received with regard to the scam and those named in the complaints include Dikshit and Kejriwal. He said both Dikshit and Kejriwal will be quizzed.
