Bhavana Arora, who had staged an ink attack on Kejriwal in January, hurled a slipper at the AAP leaders' car outside the Income Tax office here at around 3.15 pm.
However, the slipper only hit the vehicle in which the Health Minister was travelling along with AAP leaders Sanjay Singh and Ashutosh as its windows were closed.
Jain on Tuesday appeared before I-T Department and was questioned by its investigating officers for over three hours in connection with a tax evasion probe against certain Kolkata-based firms.
"How could the AAP demand proof of surgical strikes from the Indian Army? Are they agents of Pakistan?," Arora told reporters here after hurling her slipper at Jain's vehicle.
Arora belongs to Aam Aadmi Sena, a breakaway faction of the Aam Aadmi Party. However, she was not detained by the police after the incident.
Arora had also thrown ink on Kejriwal in January this year while he was delivering a speech at a public meeting in Chhatrasal Stadium.
Volunteers of the Sena had reached the Central Revenue Building at I P Estate where I-T Department office is located after they got to know about Jain appearing before the department.
Jain was last week summoned by the IT to furnish personal financial details and ITRs for the last four years.
