S. Selvanagarathinam was born on May 31, 1986, in the city of Chennai, in the state of Tamil Nadu, India.

His mother’s hardships taught him to be strong and have a clear purpose in life, which in turn, contributed to his ambitions in public service.

Challenges and Controversies

He has denied these accusations and has taken the disciplinary actions against him to court.

The matter is still in the legal process by 2025, and the public has not heard any final decision.
