Two persons were booked for threatening an ink attack on Maharashtra minister and senior Bharatiya Janata Party leader Chandrakant Patil, who incidentally wore a face shield while attending a function in Pimpri Chinchwad here on Saturday.

Action was taken on the basis of a social media message against Patil, on whom ink was thrown recently over his statement that social reformers Babasaheb Ambedkar and Jyotiba Phule "begged" for funds rather than depending on government grants to run educational institutions.
