I have seen one head constable attached to Mambalam traffic police station (I don't know his name)he is lean built and used to work at various locations at TNagar.After so many years, two months back I saw him near Pothyjunction of TNagar. I could see that even though he is promoted as sub inspector, working with same zeal and enthusiasm.I do not know his name,nor took time time to note in those busy junctions. Anyway hè is another a super cop indeed. Really a appreciable quality with soft spoken and with less words with public.
