Metropolitan Magistrate Sunil Kumar sent Bhawna Arora, a woman from the Aam Aadmi Party's breakaway group in Punjab, to 14 days' judicial custody after Delhi Police informed him that she is not required for further custodial interrogation.
Arora was arrested on Monday after she threw ink at Kejriwal, alleging a "CNG scam" in the AAP government. She, however, missed him. The incident took place at an event held here to mark the "success" of the odd-even traffic restriction scheme.
Kejriwal, who was speaking at the gathering held at the city's Chhatrasal Stadium, remained unruffled.
After the ink attack on the Aam Aadmi Party leader, accusation attacks broke out between the Bharatiya Janata Party and the Aadmi Aadmi Party with the latter accusing BJP of attempting to assassinate its leader.
