"Mahender Kumar Tokas shot himself with his licensed pistol on his head at his house in Munirka village. He was rushed to AIIMS but he was declared brought dead," a senior official said, adding a suicide note was also found.
In the note, Tokas, who also runs a public welfare trust, allegedly blamed the government for not allowing him to "do noble work".
He is survived by his wife and two sons, who run a property business.
