The AAP leader said he can't speak ill about Hazare, whom he revered as a father figure and guru, and filed a complaint against it in the cyber crime cell.
"I can never think of criticising Anna. Somebody had faked my Twitter account and posted comments against him," he said, adding it is "an attempt to malign me".
The AAP leader, who had defeated Delhi Chief Minister Sheila Dikshit in recent assembly elections, has been active on the micro-blogging site and had been posting comments on various issues.
