Nearly a week after a woman's body, stuffed in a sack, washed up on Aksa beach, the police have arrested her father-in-law and two men on the charge of killing her. Main suspect Kamal Rai, 55, told the police that he was angry after his son married victim Nandini Thakur, who belonged to a different caste.

"The couple got married three years ago. Kamal said his family was ostracised in their native place in Bihar after his son's marriage," said a police source. On December 9, when his son Pankaj went to their hometown, Kamal gave Rs 70,000 to two auto drivers - Krishna Singh, 30, and Pradeep Gupta, 40, - to kill Nandini, the source added.
