My parents are not giving my properties

Hi everyone, I eloped from my house and did intercaste marriage 3 months before. My parents didn't accept my marriage. Before marriage, my parents and relatives beats me and threatened that they will kill me and my husband if I marry him. They kept me under house arrest at that time. They took all my original documents and I worked on that time so they took my company properties also. I am not able to tolerate their torture so I eloped and did marriage. After marriage,I file complaint against them immediately for threatening and I asked in police station to return my properties,but they told that they will not give until I return home. After 3 months,they again started threatening me,their only aim is to kill me and my husband. They found my address and asked some rowdies to kidnap me. I am not able to go outside because they are ready to kill me anytime. They are not allowing me to live my life happily. I am feeling too stressed. Is there anyway to file a complaint against my parents and relatives and get back my original certificates and company properties. They told they will return company asset if I resign so I apply for resignation also because of their threatening. But now they are returning the company asset. Please I need some advice in this.
