The woman, who appeared to be in her 20s, came close to the lectern when Kejriwal was delivering his speech and showed some papers to him.
After some time, she threw ink at Kejriwal but it fell short of him though stains could be seen on the lectern. Police whisked away the woman, who was interrogated at the Model Town police station.
Following the attack, Kejriwal appealed to authorities to "let her go" after accepting "the documents that she is having".
Later, Kejriwal asked those around him to look into the grievances of the woman.
