In the FIR, Praja said that Dutta had locked her in the police quarters restroom and poured boiling water on her. 'Dutta has been abusing me for a few days and has intimidated me into keeping quiet. She is a high-ranking police officer, and I lacked the nerve to challenge her. But now, things have gone too far, and I think they'll only become worse if I don't stand up for my own safety,' she added. /IANS
