my sister in law is harrasing my aged senior citizen parents since many years, she once slaped my mom, & on 26/1 she throwed a steel glass on my mother forehead & blood started to flow we immediately filed a criminal suite against her in court. Now yesterday when she received a summons copy she lost his temper and gave my poor parents threats to kill. My brother is staying elsewhere nearby our house on rented basis since 5 months he told her wife to accompany him but she bluntly refused. My parents are under fear since she gave threats to kill.when my sister in law came back to our house at night my mother told her to accompany your husband & we will not allow you to enter our house.She is sitting full day at our flat passage. what steps should be taken now? House is in the name of my parents . she has also filed a vague case under DV.
