Innocent Divya Under Arrest?

Divya, an educated independent girl, runs a boutique, against her father’s wishes. Next to her boutique, is Shabnam’s drug hub, which invites all sorts of miscreants. This affects Divya’s business, and her complaints to the police seem useless. One day, Shabman has her accomplices attack Divya, and when Divya goes to file a complaint, the cops arrest her instead of her attackers. What leads to this arrest?
