The National Commission for Women (NCW) has pulled up West Bengal's Birbhum district police for submitting a "grossly inadequate" action taken report (ATR) in connection with the case involving Trinamool Congress leader Anubrata Mondal, who was allegedly heard hurling "filthy, unspeakable abuses" at a police officer in a viral audio clip.

In a strongly worded second letter sent on Tuesday to Birbhum SP, the commission expressed "serious dissatisfaction" with the police response and directed the district authorities to submit a revised ATR within five working days.

"While an ATR has been received, it is grossly inadequate in substance and fails to comply with the requisitions made by the Commission," NCW member Archana Majumdar wrote.
