 After committing the crimes, on Sajal's directions, his friends cleaned their weapons with mustard oil and neatly organised them on the table.Exhausted with the exertion, they ate a few Bengali sweets from the refrigerator, and left a few coins on the table as "payment" for the food, an idea that had occurred to Sajal from watching a television programme.Before Sajal's friends left, they tied him up to a chair and gagged him, to give the appearance that he was a victim too.
