Kejriwal came out of his office and had a brief chat with Harsh Vardhan. The Bharatiya Janata Party said the protest would continue till Bharti was sacked.
The protests follow what critics say was a vigilante foray by Bharti into a south Delhi neighbourhood at night following complaints from residents about a drug-and-prostitution ring allegedly involving some Africans.
The campaign led to a stand-off with Delhi Police, eventually forcing Kejriwal to stage a controversial protest against the police in the city. A lawyer by training, Bharti has denied any wrongdoing.
