A Delhi court on Wednesday sent Rohit Shekhar Tiwari's wife Apoorva to two-day police custody. Earlier today, Apoorva was arrested on charges of Rohit's murder, citing a "turbulent and unhappy" marriage as the motive. Rohit Shekhar, the son of the late veteran politician N D Tiwari, was smothered to death on the intervening night of April 15 and 16, an autopsy report said.
