The high court, which ordered a fresh probe into the case on Tuesday, May 18, has given the CBI four months to submit its report in connection with the death of computer graphics teacher Rizwanur.
Rizwanur was found dead in Sep 2007 on the railway tracks between Biddhanagar Road and Dum Dum Junction. His death came one month after he married a girl called Priyanka.
While the police concluded that Rizwanur committed suicide, the deceased's family asserted that Rizwanur was killed.
The family, therefore, moved courts for CBI inquiry into the death of Rizwanur.
The main accused in the case include Priyanka's father Ashok Todi, an industrialist in Kolkata, and her uncle Pradip Todi.
The supreme court earlier granted bail to them but had asked them to surrender their passports, and not to move out of Kolkata without permission from the CBI.
CBI has slapped charges of abetment of suicide, criminal intimidation and conspiracy on Ashok Todi and his two relatives, Pradip Todi and Anil Saraogi, Rizwanur's family friend Pappu and three police officers, former Deputy Commissioner Ajoy Kumar, ACP Sukanti Chakraborty and Sub-Inspector Krishnendu Das.
The apex court has also restricted the accused from communicating or influencing witnesses.
