Kejriwal told the Delhi assembly that he was unable to act against incidents of corruption of the Congress period because he did not have the ACB with him any more.
That is when Modi sent paramilitary forces to take control of the ACB, the chief minister said.
"The ACB is not in our hands," he pointed out, giving reasons why a probe had not been ordered into the so-called water tanker scam.
"Everyone knows that the Congress and BJP (Bharatiya Janata Party) are hand in glove (over corruption issues)," he said. "They are like 'pati and patni' (husband and wife)."
Kejriwal spoke after BJP legislator Vijender Gupta dramatically stood on the bench to demand action by the Kejriwal government on the water tanker scam that had taken place during the earlier Congress regime.
The chief minister accused the BJP -- the party has three legislators in Delhi, of which one, O.P. Sharma, has been barred from attending the house -- of doing nothing but creating a ruccus.
"They also know how to abuse women," he said, in a clear reference to Sharma, who has been suspended from the house for two sessions on charges of using derogatory language about AAP woman legislator Alka Lamba.
