A new twist has surfaced in the death of Rizwanur Rehman, the 30-year-old graphics designer in Kolkata who died in unnatural circumstances on September 21. In a string of letters signed jointly by Rizwanur and his wife Priyanka to several police officers, the young couple had said that they were afraid Priyanka's father, Ashok Todi, may hire anti-socials or criminals to try and kidnap them.
