While questioning 16 people arrested in the case, many of them serving government servants, the CB-CID found that Jayakumar, the missing mastermind behind the operation had even manipulated the Group II A exam in August 2017, helping four family members of police head constable Sithandi crack the exams the dubious way and join government service. Here again, special pens with fading inks, supplied by Jayakumar, had been used to mark the answer-sheets at the same test centre. Both Jayakumar and Sithandi are on the run.
