False Document

Biswajit Roy a well-known liar and fraud person in our locality. I am 48 now, his younger brother Avijit Roy, my childhood co-player is 2 yrs. senior to me and Biswajit Roy is about 10 yrs. elder than Avijit Roy. Few years back Biswajit Roy was working in Air-India as a temporary worker. In the year 2017 or 2018 he became permanent employee there. In the meantime by slip of tongue he revealed that his job tenure is another 10 yrs. Thereafter he made a habit of making story of known and unknown persons how they managed to change their date of birth and how they were using false document without any legal punishment. According to him ‘ALL are doing this’. Now he has become very arrogant type person. Insulting others with wrong words is a full time habit and his smart act of fraudulence with others is just awesome. I can understand that he did something wrong with his date of birth and submitted false document in support of his false age which is lesser than actual. Is there any way to bring out the truth and put him to face legal punishment in order to give meaningful message to the society?
