Hello,
I worked at Infosys from 2010 to 2013 before going to study in Ireland. During this time, the company owners and managers, along with the Karnataka police and airport police in Bangalore, spread rumors about me being a criminal to white people. As a result, I lost money and my investment. Now, I am deliberately traveling abroad again through the same city to see if they attempt to defraud me again.
Additionally, NRI parents have been contacting my Reddy and other caste roommates, telling them that I am a criminal. They even went to my college to support these claims. This situation arose because I scolded those who misbehaved with me. In the past, I used to frequent places where many bad people hung out, leading them to believe I was one of them and spreading rumors about me.
What type of police complaints should I file against my former employers and the Indian NRIs for the fraud they committed? They are also spreading rumors that I am uneducated, and even lecturers are involved in this. This is complaint on Indian masses and Indian exodus.
