For more than a year, 20-year-old Sadhna and 25-year old Pradeep have been sitting at home after clearing medical entrance examinations because they were arrested in the Vyapam scam by the police. The siblings were among the around 1,300 candidates and parents arrested by the Special Task Force, which was probing the case of irregularities in recruitments for various government jobs by the Madhya Pradesh Professional Examination Board, or Vyapam, before it was handed to the CBI this year.
