BHUBANESWAR: A team of Chennai police on Sunday launched searches at several locations across Odisha in pursuit of a couple suspected of murdering a Jagatsinghpur woman and disposing of her mutilated remains in a suitcase aboard the Tamil Nadu Express.The severed body parts of Hayathun Nisha, 38, from Jagatsinghpur district, were first recovered from a red trolley bag at Agra railway station on August 5. Subsequent investigation led police to her rented home in Guduvanchery, Chennai, where more body parts were recovered last Friday.A senior Odisha police officer said Nisha worked for a private firm in Chennai and shared the rented accommodation with Manik Uddin Laskar, a native of Assam, and Bhagabati Majhi, from Odisha.“Believing they may have fled to Odisha, Chennai police have sought our cooperation to track them down,” the officer said.The case came to light after railway staff at Agra station found the decomposed and beheaded remains in the rear general compartment of Train No. 12621, Tamil Nadu Express, on August 5. The Agra Government Railway Police registered a case and later established the identity of the victim as Nisha.As part of the investigation, the Government Railway Police at Chennai Central and the Railway Protection Force’s Crime Intelligence Branch examined CCTV footage from Platform 4. The footage showed a man and a woman boarding the train around 10 pm on August 3 with a trolley bag resembling the one in which Nisha’s remains were later found. The two suspects subsequently got off the train.Acting on these leads, investigators traced the couple’s rented house in Guduvanchery on Friday and alerted the local police. A search of the premises allegedly led to the recovery of additional body parts kept inside a large box.Chennai police are now conducting searches at different locations in Odisha to trace the suspected couple.
