Investigation must be thoroughNow-a-days the activities of our law-enforcing agents bring to my mind a few lines from the Dance Drama Shayama written by Rabindranath Tagore.Those are “chor chai, jey Korei hok, hok na shey jey kono lok”. Meaning” we want a thief, by any means, it does not matter who he is.””On February11, 2012 journalist couple Sagar-Runi were brutally murdered in their flat, it is going to be almost four years but police still have no clue who are the killers.But suddenly they became very efficient, on September 28,2015 an Italian national was murdered at Gulshan Diplomatic area and within a month police was able to nab the criminals, they arrested four youths, including three hit men who took part in the shooting. Police also said that a “Boro Bhai “hired them. One of the arrestees, however, Rubel said that he was tortured to make a confessional statement.Police must not beat around the bush and put all their efforts to nab the actual killers and bring them to justice.Nur JahanChittagong
