"Isn't a drug, prostitution and sex racket active in Khirki extension?" Kejriwal said addressing a jansabha at Begumpur in Malviya Nagar constituency.
Alleging that Bharti had faced a lot of "injustice" from the media, Kejriwal said, when people approached Bharti for help at midnight, he helped them, unlike ministers from other parties.
"He could have told people that he will come in the morning and slept off under a warm quilt like any other minister. But he did not. Anything could have happened to him? You wont find such a minister in India," Kejriwal said.
Following the controversy, Kejriwal had strongly backed Bharti resisting pressure from other quarters to sack him.
