A couple allegedly strangulated a 72-year-old woman to death, hacked the body into pieces and dumped it in a canal for seeking repayment of Rs 1.5 lakh they had borrowed from her, police said on Wednesday. The accused, Anil and Kamini Arya, residents of Gurdwara Road in Delhi's Mohan Garden, were nabbed from Uttar Pradesh's Bareilly and later arrested, they said.

On July 3, the victim's daughter-in-law filed a missing complaint with the police. Suspicion fell on the couple who were seen in CCTV footage exiting the victim's house with two heavy bags and were missing since July 3. An investigation led police to an autorickshaw driver who revealed that the couple, carrying the heavy bags, had hired his vehicle on the morning of July 1 to go to their friend's place, an officer said.
