He was arrested by the Madhya Pradesh Police and made an accused in the case. Anderson got bail from the local court and was sent to Delhi in a state government plane on December 7, 1984.The then Chief Minister Arjun Singh has claimed that the decision to let go Anderson was taken in the view of worsening law and order situation in the disaster-hit city.
